 that is performed by a small number of performers with one performer to a part. The word "chamber" signifies that the music can be performed in a small room, often in a private salon with an intimate atmosphere. However, it usually does not include, by definition, solo instrument performances.

Because of its intimate nature, chamber music has been described as "the music of friends." For more than 200 years, chamber music was played primarily by amateur musicians in their homes, and even today, when most chamber music performance has migrated from the home to the concert hall, there are still many musicians, amateur and professional, who continue to play chamber music for their own pleasure. Playing chamber music requires special skills, both musical and social, which are different from the skills required for playing solo or symphonic works.

 described chamber music (specifically, string quartet music) as "four rational people conversing." This conversational paradigm has been a thread woven through the history of chamber music composition from the end of the 18th century to the present. The analogy to conversation recurs in descriptions and analyses of chamber music compositions.

History of chamber music

From its earliest beginnings in the Medieval period to the present, chamber music has been a reflection of the changes in the technology and the society that produced it.

Early beginnings

During the Middle Ages and the early Renaissance, instruments were used primarily as accompaniment for singers. String players would play along with the melody line sung by the singer. There were also purely instrumental ensembles, often of stringed precursors of the violin family, called consorts
Consort of instruments
A consort of instruments was a phrase used in England during the sixteenth and seventeenth centuries to indicate an instrumental ensemble. These could be of the same or a variety of instruments. Consort music enjoyed considerable popularity at court and in households of the wealthy in the...

Because each instrument was playing essentially the same melodies, all the instruments were equal.

The harmonic role played by the keyboard or other chording instrument was subsidiary, and usually the keyboard part was not even written out; rather, the chordal structure of the piece was specified by numeric codes over the bass line, called figured bass

 style, with "thinner texture, ... and clearly defined melody and bass" to the complexities of counterpoint. Now a new custom arose, that gave birth to a new form of chamber music: the serenade. Patrons invited street musicians to play evening concerts below the balconies of their homes, their friends and their lovers. Patrons and musicians commissioned composers to write suitable suites of dances and tunes, for groups of two to five or six players. These works were called serenades (sera=night), nocturnes, divertimenti, or cassations (from gasse=street). The young Joseph Haydn was commissioned to write several of these.

Haydn, Mozart, and the classical style

Joseph Haydn
Joseph Haydn
Franz Joseph Haydn , known as Joseph Haydn , was an Austrian composer, one of the most prolific and prominent composers of the Classical period. He is often called the "Father of the Symphony" and "Father of the String Quartet" because of his important contributions to these forms...

 is generally credited with creating the modern form of chamber music as we know it. In 83 string quartets, 45 piano trios, and numerous string trios, duos and wind ensembles, Haydn established the conversational style of composition and the overall form that was to dominate the world of chamber music for the next two centuries.
An example of the conversational mode of composition is Haydn's string quartet Op. 20, No. 4 in D major. In the first movement, after a statement of the main theme by all the instruments, the first violin breaks into a triplet figure, supported by the second violin, viola and cello. The cello answers with its own triplet figure, then the viola, while the other instruments play a secondary theme against this movement. Unlike counterpoint, where each part plays essentially the same melodic role as the others, here each instrument contributes its own character, its own comment on the music as it develops.

Haydn also settled on an overall form for his chamber music compositions, which would become the standard, with slight variations, to the present day. The characteristic Haydn string quartet has four movements:
An opening movement in sonata form

, usually with two contrasting themes, followed by a development section where the thematic material is transformed and transposed, and ending with a recapitulation of the initial two themes.

His innovations earned Haydn the title "father of the string quartet", and he was recognized by his contemporaries as the leading composer of his time. But he was by no means the only composer developing new modes of chamber music. Even before Haydn, many composers were already experimenting with new forms. Giovanni Battista Sammartini

 greatly expanded its vocabulary. His chamber music added numerous masterpieces to the chamber music repertoire. Mozart's seven piano trios and two piano quartets were the first to apply the conversational principle to chamber music with piano. Haydn's piano trios are essentially piano sonatas with the violin and cello playing mostly supporting roles, doubling the treble and bass lines of the piano score. But Mozart gives the strings an independent role, using them as a counter to the piano, and adding their individual voices to the chamber music conversation.

From home to hall

The turn of the 19th century saw dramatic changes in society and in music technology which had far-reaching effects on the way chamber music was composed and played.

The collapse of the aristocratic system. Throughout the 18th century, the composer was normally an employee of an aristocrat, and the chamber music he composed was for the pleasure of and the performance by aristocratic amateurs. Haydn, for example, was an employee of the Count Nikolaus Esterházy

With the bankruptcy of the aristocracy and new social orders throughout Europe, composers increasingly had to make their own ways by selling and performing their compositions. They often gave subscription concerts, renting a hall and collecting the receipts from the performance. Increasingly, chamber music was written not only to be performed by rich amateurs, but to be performed by professional musicians to a paying audience.

 composed and tore up 20 string quartets before he dared publish a work that he felt was worthy of the "giant marching behind."

Beethoven made his formal debut as a composer with three Piano Trios, Op. 1. Even these early works, published when Beethoven was only 22, while adhering to a strictly classical mold, showed signs of the new paths that Beethoven was to forge in the coming years. When he showed the manuscript of the trios to Haydn, his teacher, prior to publication, Haydn approved of the first two, but warned against publishing the third trio, in C minor, as too radical, warning it would not "be understood and favorably received by the public." In fact, Haydn's prediction was wrong; the third trio proved to be the most popular of the set, and Haydn's criticisms caused a falling out between him and the sensitive Beethoven. The trio is, indeed, a departure from the mold that Haydn and Mozart had formed. Beethoven makes dramatic deviations of tempo within phrases and within movements. He greatly increases the independence of the strings, especially the cello, allowing it to range above the piano and occasionally even the violin.

If his Op. 1 trios introduced Beethoven's works to the public, his Septet, Op. 20

, established him as one of Europe's most popular composers. The septet, scored for violin, viola, cello, contrabass, clarinet, horn and bassoon, was a huge hit. It was played in concerts again and again. It appeared in transcriptions for many combinations — one of which, for clarinet, cello and piano, was written by Beethoven himself — and was so popular that Beethoven feared it would eclipse his other works. So much so that by 1815, Carl Czerny

 wrote that Beethoven "could not endure his septet and grew angry because of the universal applause which it has received." The septet is written as a classical divertimento in six movements, including two minuets, and a set of variations. It is full of catchy tunes, with solos for everyone, including the contrabass.
In his 17 string quartets, composed over the course of 37 of his 56 years, Beethoven goes from classical composer par excellence to creator of musical Romanticism, and finally transcends classicism and romanticism to create a genre that defies categorization. Stravinsky referred to the Große Fuge

. Even here, Beethoven stretched the formal structures pioneered by Haydn and Mozart. In the quartet Op. 18, No. 1, in F major, for example, there is a long, lyrical solo for cello in the second movement, giving the cello a new type of voice in the quartet conversation. And the last movement of Op. 18, No. 6, "La Malincolia", creates a new type of formal structure, interleaving a slow, melancholic section with a manic dance. Beethoven was to use this form in later quartets, and it was adopted by Brahms and others as well.
In the years 1805–1806, Beethoven composed the three Op. 59
String Quartets Nos. 7 - 9, Opus 59 - Rasumovsky (Beethoven)
The three "Rasoumovsky" string quartets, opus 59, are the quartets Ludwig van Beethoven wrote in 1806, as a result of a commission by the Russian ambassador in Vienna, Count Andreas Razumovsky:*String Quartet No. 7 in F major, Op. 59, No. 1...

, the "Serioso."

The Serioso is a transitional work that ushers in Beethoven's late period — a period of compositions of great introspection. "The particular kind of inwardness of Beethoven's last style period," writes Joseph Kerman, gives one the feeling that "the music is sounding only for the composer and for one other auditor, an awestruck eavesdropper: you." In the late quartets, the quartet conversation is often disjointed, proceeding like a stream of consciousness. Melodies are broken off, or passed in the middle of the melodic line from instrument to instrument. Beethoven uses new effects, never before essayed in the string quartet literature: the ethereal, dreamlike effect of open intervals between the high E string and the open A string in the trio of Op. 132; the use of sul ponticello (playing on the bridge of the violin) for a brittle, scratchy sound in the Presto movement of Op. 131; the use of the lydian mode, unheard in Western music for 200 years, in Op. 132; a cello melody played high above all the other strings in the finale of Op. 132. Yet for all this disjointedness, each quartet is tightly designed, with an overarching structure that ties the work together.

Beethoven wrote eight piano trios, five string trios, two string quintets, and numerous pieces for wind ensemble. He also wrote 10 sonatas for violin and piano and five sonatas for cello and piano.

, Schumann writes a double fugue in the finale, using the theme of the first movement and the theme of the last movement. Both Schumann and Mendelssohn, following the example set by Beethoven, revived the fugue, which had fallen out of favor since the Baroque period. However, rather than writing strict, full-length fugues, they used counterpoint as another mode of conversation between the chamber music instruments. Many of Schumann's chamber works, including all three of his string quartets and his piano quartet have contrapuntal sections interwoven seamlessly into the overall compositional texture.

The composers of the first half of the 19th century were acutely aware of the conversational paradigm established by Haydn and Mozart. Schumann wrote that in a true quartet "everyone has something to say... a conversation, often truly beautiful, often oddly and turbidly woven, among four people." Their awareness is exemplified by composer and virtuoso violinist Louis Spohr

Chamber music and society in the 19th century

The middle of the 19th century saw more changes in society and in musical tastes, which had their impact on chamber music composition and performance.

While improvements in instruments led to more public performances of chamber music, it remained very much a type of music to be played as much as performed. Amateur quartet societies sprang up throughout Europe, and no middling-sized city in Germany or France would be without one. These societies sponsored house concert

s, compiled music libraries, and encouraged the playing of quartets and other ensembles. Thousands of quartets were published by hundreds of composers; between 1770 and 1800, more than 2000 quartets were published, and the pace did not decline in the next century.

Toward the 20th century

It was Johannes Brahms who carried the torch of Romantic music toward the 20th century. Heralded by Robert Schumann as the forger of "new paths" in music, Brahms's music is a bridge from the classical to the modern. On the one hand, Brahms was a traditionalist, conserving the musical traditions of Bach and Mozart. Throughout his chamber music, he uses traditional techniques of counterpoint, incorporating fugues and canons into rich conversational and harmonic textures. On the other hand, Brahms expanded the structure and the harmonic vocabulary of chamber music, challenging traditional notions of tonality. An example of this is in the Brahms second string sextet, Op. 36
String Sextet No. 2 (Brahms)
Johannes Brahms' String Sextet No. 2 in G major, Opus 36 was composed during the years of 1864-1865 and published by the firm of Fritz Simrock.It was first performed in Boston, Massachusetts on October 11, 1866....

. Traditionally, composers wrote the first theme of a piece in the key of the piece, firmly establishing that key as the tonic, or home, key of the piece. The opening theme of Op. 36 starts in the tonic (G major), but already by the third measure has modulated to the unrelated key of E flat major. As the theme develops, it ranges through various keys before coming back to the tonic G major. This "harmonic audacity", as Swafford describes it, opened the way for bolder experiments to come.
Not only in harmony, but also in overall musical structure, Brahms was an innovator. He developed a technique that Arnold Schoenberg described as "developing variation". Rather than discretely defined phrases, Brahms often runs phrase into phrase, and mixes melodic motives to create a fabric of continuous melody. Schoenberg, the creator of the 12-tone system of composition, traced the roots of his modernism to Brahms, in his essay "Brahms the Progressive".

All told, Brahms published 24 works of chamber music, including three string quartets, five piano trios, the quintet for piano and strings, Op. 34

. Violist James Dunham, of the Cleveland and Sequoia Quartets, writes of the Ravel quartet, "I was simply overwhelmed by the sweep of sonority, the sensation of colors constantly changing..." For these composers, chamber ensembles were the ideal vehicle for transmitting this atmospheric sense, and chamber works constituted much of their oeuvre.

Nationalism in chamber music

Parallel with the trend to seek new modes of tonality and texture was another new development in chamber music: the rise of nationalism. Composers turned more and more to the rhythms and tonalities of their native lands for inspiration and material. "Europe was impelled by the Romantic tendency to establish in musical matters the national boundaries more and more sharply," wrote Alfred Einstein. "The collecting and sifting of old traditional melodic treasures ... formed the basis for a creative art-music." For many of these composers, chamber music was the natural vehicle for expressing their national characters.

New sounds for a new world

The end of western tonality, begun subtly by Brahms and made explicit by Debussy, posed a crisis for composers of the 20th century. It was not merely an issue of finding new types of harmonies and melodic systems to replace the diatonic scale
Diatonic scale
In music theory, a diatonic scale is a seven note, octave-repeating musical scale comprising five whole steps and two half steps for each octave, in which the two half steps are separated from each other by either two or three whole steps...

 that was the basis of western harmony; the whole structure of western music — the relationships between movements and between structural elements within movements — was based on the relationships between different keys. So composers were challenged with building a whole new structure for music.

This was coupled with the feeling that the era that saw the invention of automobiles, the telephone, electric lighting, and world war needed new modes of expression. "The century of the aeroplane deserves its music," wrote Debussy.

Inspiration from folk music

The search for a new music took several directions. The first, led by Bartók, was toward the tonal and rhythmic constructs of folk music. Bartók's research into Hungarian and other eastern European and Middle Eastern folk music revealed to him a musical world built of musical scales that were neither major nor minor, and complex rhythms that were alien to western music. In his fifth quartet, for example, Bartók uses a time signature of , "startling to the classically-trained musician, but second-nature to the folk musician." Structurally, also, Bartók often invents or borrows from folk modes. In the sixth string quartet, for example, Bartók begins each movement with a slow, elegiac melody, followed by the main melodic material of the movement, and concludes the quartet with a slow movement that is built entirely on this elegy. This is a form common in many folk music cultures.
Bartók's six string quartets are often compared with Beethoven's late quartets. In them, Bartók builds new musical structures, explores sonorities never previously produced in classical music (for example, the snap pizzicato, where the player lifts the string and lets it snap back on the fingerboard with an audible buzz), and creates modes of expression that set these works apart from all others. "Bartók's last two quartets proclaim the sanctity of life, progress and the victory of humanity despite the anti-humanistic dangers of the time," writes analyst John Herschel Baron. The last quartet, written when Bartók was preparing to flee the Nazi invasion of Hungary for a new and uncertain life in the U.S., is often seen as an autobiographical statement of the tragedy of his times.

The musical use of more than one key simultaneously is polytonality . Bitonality is the use of only two different keys at the same time...

, that is, music where different instruments play in different keys at the same time. Milhaud wrote 18 string quartets; quartets number 14 and 15 are written so that each can be played by itself, or the two can be played at the same time as an octet. Milhaud also used jazz idioms, as in his Suite for clarinet, violin and piano.

Charles Ives used not only polytonality in his chamber works, but also polymeter. In his first string quartet
String Quartet No. 1 (Ives)
String Quartet No. 1 is one of the most studied works by composer Charles Ives. The piece is composed for the standard string quartet of two violins, a viola, and a cello. There are four movements:*I. Andante con moto*II. Allegro*III. Adagio cantabile...

 he writes a section where the first violin and viola play in time while the second violin and cello play in .

Neoclassicism

The plethora of directions that music took in the first quarter of the 20th century led to a reaction by many composers. Led by Stravinsky, these composers looked to the music of preclassical Europe for inspiration and stability. While Stravinsky's neoclassical works — such as the Double Canon for String Quartet — sound contemporary, they are modeled on Baroque and early classical forms — the canon, the fugue, and the Baroque sonata form.

 was another neoclassicist. His many chamber works are essentially tonal, though they use many dissonant harmonies. Hindemith wrote seven string quartets and two string trios, among other chamber works. At a time when composers were writing works of increasing complexity, beyond the reach of amateur musicians, Hindemith explicitly recognized the importance of amateur music-making, and intentionally wrote pieces that were within the abilities of nonprofessional players.

 is an autobiographical work, that expresses his deep depression from his ostracization, bordering on suicide: it quotes from previous compositions, and uses the four-note motif DSCH, the composer's initials.

Stretching the limits

As the century progressed, many composers created works for small ensembles that, while they formally might be considered chamber music, challenged many of the fundamental characteristics that had defined the genre over the last 150 years.

The music of friends: The idea of composing music that could be played at home has been largely abandoned. Bartók was among the first to part with this idea. "Bartók never conceived these quartets for private performance but rather for large, public concerts." Aside from the many almost insurmountable technical difficulties of many modern pieces, some of them are hardly suitable for performance in a small room. For example, Different Trains
Different Trains
Different Trains is a three-movement piece for string quartet and tape written by Steve Reich in 1988. It won a Grammy Award in 1990 for Best Contemporary Classical Composition.The work's three movements have the following titles:...

 is scored for live string quartet and recorded tape, which layers together a carefully orchestrated cacophony of speech, recorded train sounds, and three string quartets.

The conversational paradigm: How can the players of a string quartet conduct a conversation when they are flying over the audience in four separate helicopters? This is the case in the Helikopter-Streichquartett
Helikopter-Streichquartett
The Helikopter-Streichquartett is one of Karlheinz Stockhausen's best-known pieces, and one of the most complex to perform. It involves a string quartet, four helicopters with pilots, as well as audio and video equipment and technicians. It was first performed and recorded in 1995...

 to enable them to play at the right time.

The relation of composer and performer: Traditionally, the composer wrote the notes, and the performer interpreted them. But this is no longer the case in much modern music. In Für Kommende Zeiten
Aus den Sieben Tagen
Aus den sieben Tagen is a collection of 15 text compositions by Karlheinz Stockhausen, composed in May 1968, in reaction to a personal crisis, and characterized as "Intuitive music"—music produced primarily from the intuition rather than the intellect of the performer...

(For Times to Come), Stockhausen writes poetic, cryptic instructions to the performers, who must then improvise this new form of "intuitive" music. "Star constellations/with common points/and falling stars... Abrupt end" is a sample.

Composer Terry Riley describes how he works with the Kronos Quartet, an ensemble devoted to contemporary music: "When I write a score for them, it's an unedited score. I put in just a minimal amount of dynamics and phrasing marks... we spend a lot of time trying out different ideas in order to shape the music, to form it. At the end of the process, it makes the performers actually own the music. That to me is the best way for composers and musicians to interact."

New sounds: Composers seek new timbres, remote from the traditional blend of strings, piano and woodwinds that characterized chamber music in the 19th century. This search led to the incorporation of new instruments, such as the theremin

, for electric string quartet. The players not only bow their amplified instruments, they also beat on them with thimbles, pluck them with paperclips, and play on the wrong side of the bridge or between the fingers and the nut.

What do these changes mean for the future of chamber music? "With the technological advances have come questions of aesthetics and sociological changes in music," writes analyst Baron. "These changes have often resulted in accusations that technology has destroyed chamber music and that technological advance is in inverse proportion to musical worth. The ferocity of these attacks only underscores how fundamental these changes are, and only time will tell if humankind will benefit from them."

Chamber music in contemporary society

Analysts agree that the role of chamber music in society has changed profoundly in the last 50 years; yet there is little agreement as to what that change is. On the one hand, Baron contends that "chamber music in the home... remained very important in Europe and America until the Second World War, after which the increasing invasion of radio and recording reduced its scope considerably." This view is supported by subjective impressions. "Today there are so many more millions of people listening to music, but far fewer playing chamber music just for the pleasure of it," says conductor and pianist Daniel Barenboim

.

However, recent surveys suggest there is, on the contrary, a resurgence of home music making. In the radio program "Amateurs Help Keep Chamber Music Alive" from 2005, reporter Theresa Schiavone cites a Gallup poll showing an increase in the sale of stringed instruments in America. Joe Lamond, president of the National Association of Music Manufacturers (NAMM) attributes the increase to a growth of home music-making by adults approaching retirement. "I would really look to the demographics of the [baby] boomers," he said in an interview. These people "are starting to look for something that matters to them... nothing makes them feel good more than playing music."

A study by the European Music Office in 1996 suggests that not only older people are playing music. "The number of adolescents today to have done music has almost doubled by comparison with those born before 1960," the study shows. While most of this growth is in popular music, some is in chamber music and art music, according to the study.

While there is no agreement about the number of chamber music players, the opportunities for amateurs to play have certainly grown. The number of chamber music camps and retreats, where amateurs can meet for a weekend or a month to play together, has burgeoned. Music for the Love of It, an organization to promote amateur playing, publishes a directory of music workshops that lists more than 500 workshops in 24 countries for amateurs in 2008 The Associated Chamber Music Players (ACMP) offers a directory of over 5,000 amateur players worldwide who welcome partners for chamber music sessions.

Regardless of whether the number of amateur players has grown or shrunk, the number of chamber music concerts in the west has increased greatly in the last 20 years. Concert halls have largely replaced the home as the venue for concerts. Baron suggests that one of the reasons for this surge is "the spiraling costs of orchestral concerts and the astronomical fees demanded by famous soloists, which have priced both out of the range of most audiences." The repertoire at these concerts is almost universally the classics of the 19th century. However, modern works are increasingly included in programs, and some groups, like the Kronos Quartet
Kronos Quartet
Kronos Quartet is a string quartet founded by violinist David Harrington in 1973 in Seattle, Washington. Since 1978, the quartet has been based in San Francisco, California. The longest-running combination of performers had Harrington and John Sherba on violin, Hank Dutt on viola, and Joan...

.
Several groups have taken classical chamber music out of the concert hall, and back into the streets where it began 300 years ago. Simple Measures, a group of chamber musicians in Seattle (Washington, USA), gives concerts in shopping centers, coffee shops, and streetcars. Star FK Radium has adapted their own style of original, modern chamber music known as "music box" often played at outdoor concerts in Washington DC (USA). The Providence (Rhode Island, USA) String Quartet has started the "Storefront Strings" program, offering impromptu concerts and lessons out of a storefront in one of Providence's poorer neighborhoods. "What really makes this for me," said Rajan Krishnaswami, cellist and founder of Simple Measures, "is the audience reaction... you really get that audience feedback."

Chamber music performance

Chamber music performance is a specialized field, and requires a number of skills not normally required for the performance of symphonic or solo music. Many performers and authors have written about the specialized techniques required for a successful chamber musician. Chamber music playing, writes M.D. Herter Norton, requires that "individuals ... make a unified whole yet remain individuals. The soloist is a whole unto himself, and in the orchestra individuality is lost in numbers...".

The "music of friends"

Many performers contend that the intimate nature of chamber music playing requires certain personality traits.

David Waterman, cellist of the Endellion Quartet, writes that the chamber musician "needs to balance assertiveness and flexibility." Good rapport is essential. Arnold Steinhardt, first violinist of the Guarneri Quartet, notes that many professional quartets suffer from frequent turnover of players. "Many musicians cannot take the strain of going mano a mano with the same three people year after year."

Mrs. Norton, a violinist who studied quartet playing with the Kneisel Quartet at the beginning of the last century, goes so far that players of different parts in a quartet have different personality traits. "By tradition the first violin is the leader" but "this does not mean a relentless predominance." The second violinist "is a little everybody's servant." "The artistic contribution of each member will be measured by his skill in asserting or subduing that individuality which he must possess to be at all interesting."

Interpretation

"For an individual, the problems of interpretation are challenging enough," writes Waterman, "but for a quartet grappling with some of the most profound, intimate and heartfelt compositions in the music literature, the communal nature of decision-making is often more testing than the decisions themselves."

The problem of finding agreement on musical issues is complicated by the fact that each player is playing a different part, that may appear to demand dynamics or gestures contrary to those of other parts in the same passage. Sometimes these differences are even specified in the score — for example, where cross-dynamics are indicated, with one instrument crescendoing while another is getting softer.

One of the issues that must be settled in rehearsal is who leads the ensemble at each point of the piece. Normally, the first violin leads the ensemble. However, there are passages that require other instruments to lead. For example, John Dalley, second violinist of the Guarneri Quartet, says, "We'll often ask [the cellist] to lead in pizzicato
Pizzicato
Pizzicato is a playing technique that involves plucking the strings of a string instrument. The exact technique varies somewhat depending on the type of stringed instrument....

 passages. A cellist's preparatory motion for pizzicato is larger and slower than that of a violinist."

Players discuss issues of interpretation in rehearsal; but often, in mid-performance, players do things spontaneously, requiring the other players to respond in real time. "After twenty years in the [Guarneri] Quartet, I'm happily surprised on occasion to find myself totally wrong about what I think a player will do, or how he'll react in a particular passage," says violist Michael Tree.

Ensemble, blend and balance

Playing together constitutes a major challenge to chamber music players. Many compositions pose difficulties in coordination, with figures such as hemiola

, and fast unisons. But beyond the challenge of playing together is the greater challenge of sounding good together.

To create a unified chamber music sound — to blend — the players must coordinate the details of their technique. They must decide when to use vibrato and how much. They often need to coordinate their bowing and breathing, to ensure unity of tone. They need to agree on special techniques, such as spiccato, sul tasto, sul ponticello and so on.

Balance refers to the relative volume of each of the instruments. Because chamber music is a conversation, sometimes one instrument must stand out, sometimes another. It is not always a simple matter for members of an ensemble to determine the proper balance while playing; frequently, they require an outside listener, or a recording, to tell them that the relations between the instruments are correct.

Intonation

Chamber music playing presents special problems of intonation. The piano is tuned using equal temperament
Equal temperament
An equal temperament is a musical temperament, or a system of tuning, in which every pair of adjacent notes has an identical frequency ratio. As pitch is perceived roughly as the logarithm of frequency, this means that the perceived "distance" from every note to its nearest neighbor is the same for...

, that is, the 12 notes of the scale are spaced exactly equally. This method makes it possible for the piano to play in any key; however, all the intervals except the octave sound very slightly out of tune. String players can play with just intonation
Just intonation
In music, just intonation is any musical tuning in which the frequencies of notes are related by ratios of small whole numbers. Any interval tuned in this way is called a just interval. The two notes in any just interval are members of the same harmonic series...

, that is, they can play specific intervals (such as fifths) exactly in tune. Moreover, string and wind players can use expressive intonation, changing the pitch of a note to create a musical or dramatic effect. "String intonation is more expressive and sensitive than equal-tempered piano intonation."

However, using true and expressive intonation requires careful coordination with the other players, especially when a piece is going through harmonic modulations. "The difficulty in string quartet intonation is to determine the degree of freedom you have at any given moment," says Steinhardt.

The chamber music experience

Players of chamber music, both amateur and professional, attest to a unique enchantment with playing in ensemble. ""It is not an exaggeration to say that there opened out before me an enchanted world," writes Walter Willson Cobbett

, devoted amateur musician and editor of Cobbett's Cyclopedic Survey of Chamber Music.

Ensembles develop a close intimacy of shared musical experience. "It is on the concert stage where the moments of true intimacy occur," writes Steinhardt. "When a performance is in progress, all four of us together enter a zone of magic somewhere between our music stands and become a conduit, messenger, and missionary... It is an experience too personal to talk about and yet it colors every aspect of our relationship, every good-natured musical confrontation, all the professional gossip, the latest viola joke."

The playing of chamber music has been the inspiration for numerous books, both fiction and nonfiction. An Equal Music by Vikram Seth, explores the life and love of the second violinist of a fictional quartet, the Maggiore. Central to the story is the tensions and the intimacy developed between the four members of the quartet. "A strange composite being we are [in performance], not ourselves any more, but the Maggiore, composed of so many disjunct parts: chairs, stands, music, bows, instruments, musicians..." The Rosendorf Quartet, by Natan Shaham, describes the trials of a string quartet in Palestine, before the establishment of the state of Israel. For the Love of It by Wayne Booth is a nonfictional account of the author's romance with cello playing and chamber music.
