Pedal point
In tonal music, a pedal point is a sustained tone, typically in the bass, during which at least one foreign, i.e., dissonant harmony is sounded in the other parts. A pedal point sometimes functions as a "non-chord tone", placing it in the categories alongside suspensions, retardations, and passing...

, which refers to a prolonged bass tone under changing upper harmonies, derives from the use of the organ pedalboard to hold sustained bass notes. These earliest pedals were wooden stubs nicknamed "mushrooms" which were placed at the height of the feet. These pedals, which used simple pulldowns connected directly to the manual keys, are found in organs dating to the 13th century. The pedals on French organs were composed of short stubs of wood projecting out of the floor which were mounted in pedalboards that could be either flat or tilted. Organists were unable to play anything but simple bass lines or slow-moving plainsong

 notes (colloquially referred to as the "black" notes). The first approach can be seen in the 1361 Halberstadt organ, which uses shorter black keys which are placed above the white keys. Other organs positioned the black keys on the same level and depth as the white keys. The first pedal keyboards only had three or four notes. Eventually, organ designers augmented this range by using eight notes, an approach now called a "short octave" keyboard, because it does not include accidental notes such as C#, D#, F#, G#, and A#.

 used an F# and G# in the lowest octave of the manuals and pedal keyboards, but not a C# and D# . From the 16th to 18th centuries, short octave keyboards were also used in the lowest octave of upper manual keyboards.

By the 14th century, organ designers were building separate windchests for the pedal division, to supply the pipes with the large amount of wind that bass notes need to speak. These windchests were often built into tall structures called "organ towers." Until the 15th century, most pedal keyboards only triggered the existing Hauptwerk pipes already used by the upper manual keyboards. Beginning in the 15th century, some organ designers began giving pedal keyboards their own set of pipes and stops. In the fifteenth and sixteenth centuries, the pedal division usually consisted of a few 8' ranks and a single 16' rank. By the early 17th century, pedal divisions became more complex, with a richer variety of pipes and tones. Nevertheless, the pedal division was usually inconsistent from one country to another.

17th century to 18th century

By the beginning of the 17th century, organ designers began to give pedalboards on large organs a larger range, encompassing twenty-eight to thirty notes. As well, German organ designers began to use longer, narrower pedals, with a wider space between the pedals. By this point, most pedals were given a smoother lever-action by including a fulcrum at the back of each pedal. These design changes allowed performers to play more complex, fast-moving pedal lines. This gave rise to the dramatic pedal solos found in German organ works from composers from the Lutheran Organ School, such as J.S. Bach. In Bach's organ music the cantus firmus

, is often performed in the pedal, using a reed stop to make it stand out.

Several sources, including an encyclopedia on the organ, claim that the pedalboard design improvements of the 17th century allowed the organist to actuate the pedals either with the toe of the foot or with the heel. However, organist Ton Koopman

 argues that
"Bach's complete oeuvre [can be played] with the pedal technique of his time, in other words without the use of the heel." Koopman claims that in "Bach's day toe and heel pedalling was not yet known, as is evident from his organ works, in which all the pedal parts can be played with the toe." Interestingly, what evolved as "German" pedal technique in the late eighteenth and early 19th century promoted heel-and-toe pedaling, while the "French" style was predicated on "toe only" pedal technique.
In the 17th century and 18th century, pedalboards were rare in England. A critic for the New York Times in 1895 argued that this may explain why Handel's published organ works are generally lighter-sounding than those of J.S. Bach. In the 17th and 18th centuries, the pedal part of organ music was rarely given its own staff. Instead, the organ part would be put into two staves, which were mostly used for the upper and lower manual parts. When the composer wanted a part to be played with the pedal keyboard, they marked "Pedal", "Ped.", or simply "P". Often these signs were omitted entirely, and the player would have to decide if the range of all the parts or the lowest part was appropriate for the pedal keyboard. This lack of specification is in keeping with many other aspects of Baroque musical performance practice, such as the use of improvised chords by organists and harpsichord players in the figured bass

 tradition and the use of improvised ornaments by solo singers and instrumentalists.

19th century to 20th century

In the late 1820s, the pedalboard was still fairly unfamiliar in the UK. In the organ at the Church of St James at Bermondsey in 1829, "a finger [manual] keyboard was added for those unable to play with their feet." If an organist was performing a piece with a pedal part, "an assistant was needed to play the bottom line of the finger keyboard, offset on the bass side of the console." In 1855 in England, Henry Willis patented a concave design for the pedalboard which also radiated the ends keyboard outward and used longer keys, bringing the end keys closer to the performer. This design became widely used in the UK and in the US in the late 19th century, and by 1903, the American Guild of Organists (AGO) adopted it as their standard.

In the 19th century and early 20th century, the pedal division also underwent changes. The pedal divisions from the Baroque era had tended to include a small number of upper pedal stops, which allowed performers to perform higher-range melodies with the pedalboard. In the 19th century and early 20th century, organ designers removed most of the upper pedal stops, and used pedal divisions which were dominated by 8' and 16' stops. This design change, which coincided with the musical trend for music with a deep, rich bass part, meant that the pedalboard was used mainly for the performance of bass parts.

By the mid-19th century, the pedal part of organ music was increasingly given its own staff, which meant that organ music began being printed in three-stave systems (upper manual, lower manual, and pedal keyboard). Whereas early organ composers left the way that pedal keyboard lines were played to the discretion of the player, in the later 19th century, composers began indicating suggested foot usage.

In addition to indicating whether the left or right foot should be used, symbols indicate whether the toe or heel of the foot should be used. The toe is indicated with a "^" symbol, while the heel is indicated with a "u" or "o" symbol. Symbols below notes call for the left foot, while symbols above notes indicate the right foot.

Swedish organist L. Nilson published a method for the pedal keyboard, the English translation of which was titled A System of Technical Studies in Pedal Playing for the Organ (Schirmer, 1904). Nilson lamented that it "...is a melancholy fact that only very few eminent organists since Bach's time have made it their business to lift pedal-playing out of its primitive confusion..." (page 1 of Preface). He argued that the great organ pedagogues such as Kittel and Abbe Vogler did not make any efforts to improve the "...system of playing on the pedals". Nilson makes one exception from this critique: the organ method of J. Lemmens, who he praises as having reformed pedal playing by introducing "...sound principles of execution" (page 2 of Preface). Nilson's pedal method includes scale and arpeggio studies, polyphonic studies with both feet playing in contrary motion, studies written in parallel octaves, and studies written in thirds.

1990s-2000s

In the 1990s, standalone electronic MIDI controller

 pedalboards became widely available on the market. MIDI pedalboards do not produce any tones by themselves, and so they must be connected to a MIDI-compatible electronic keyboard or MIDI sequencer and an amplified loudspeaker to produce musical tones. In the 1990s and 21st century, some churches began using electronic-trigger equipped pedalboards for the 16' and 32' stops. The MIDI information from the electronic pedalboard sensors triggers pipe organ sounds from digital sound modules (e.g., Wicks CM-100, Ahlborn Archive Modules, or Walker Technical sound generation), which are then amplified and fed through loudspeakers.

These MIDI systems can be much less expensive than metal or wooden bass pipes, which are very costly to purchase and install, due to their heavy weight (up to one ton per pipe), large size, and need for large amounts of wind. Another rationale for using MIDI systems is that it may be easier to get a focused sound with a MIDI system, because all of the bass tone emanates from a single speaker or set of speakers. With traditional pipes, it can be difficult to give the pedal division a focused sound, because the large pipes tend to be spread out over the entire organ pipe chest.

This cost-saving measure has been the subject of controversy in the organ scene. Advocates of the use of MIDI pedal divisions argue that a good quality MIDI system will produce a better tone than an inexpensive set of bass pipes with money-saving "shortcuts" such as using stopped pipes and resultant
Resultant (organ)

 tones to reduce the number of pipes that are needed. However, critics dislike the way that the use of MIDI pedal divisions blends electronically amplified lower voices with the natural, wind-driven upper ranks. Willi Apel and Peter Williams argue that by definition, an organ must make its sound by air flowing through pipes. Some critics argue that the bass tone from a MIDI pedal division, which comes from an amplified 12" subwoofer

, is not as "natural" and "open-sounding" as the vibrations from a massive, wind-driven 32-foot pipe.

Keyboards

Pedalboards range in size from 13 notes on small spinet organs designed for in-home use (an octave, conventionally C2

-C3) to 32 notes (two and a half octaves, C2-G4) on church or concert organs. Modern pipe organs typically have 30- or 32-note pedalboards, while some electronic organs and many older pipe organs have 25-note pedalboards.

Besides the number of pedals, the two main identifying aspects of a pedalboard are: (1) whether all the pedals are at the same height relative to the floor ["flat"], or whether the pedals in the middle are lower than those on the outer edges, forming a curved-in shape ["concave"], and (2) whether all the pedals are completely parallel to each other ["parallel"], or whether the pedals are closer together at the far end than at the end closest to the organ console ["radiating"]. Specifications vary by country, organ builder, era, and individual tastes.

Pedal division

In an organ with more than one keyboard, the stops and the ranks that the stops control are separated into different divisions, in which the ranks of pipes are grouped together so that they will make a "focused" or coherent sound. The pedal division, which is played from the pedal keyboard, usually includes more stops of 16' pitch. The sound of the pedal division is generally voiced so that the pedal division will complement the sound of the Great division. Common 16' stops found in the pedal division include the 16' Bourdon, the 16' Principal, and the 16' Trombone. Eight foot stops include the 8' Open Diapason. Pedal divisions may also include higher-register stops, such as the 4' Choral Bass or various mixtures. When pedal parts are performed, a 16' stop is usually paired with an 8' one to provide more definition. For pedal parts that need accentuation, such as the Cantus Firmus melody in a 17th century organ piece, many organs have a nasal-sounding reed stop in the pedal division, or a 4' Principal designated on the stop knob as "Choralbass".

A small number of pedalboards have a pedal divide system which enables the organist to split the pedal board at its mid-point. With this system, an organist can play a melody with the right foot and a bass part with the left foot.

Controls

In some organs, a wooden panel called a "kickboard" or "kneeboard" is installed above the pedalboard, between the pedals and the lowest manual keyboard. Expression pedals, coupler controls and toe studs (to activate stops or stop combinations) may be located on or set into the kickboard. Expression pedals are used to open and close shades or shutters that enclose the pipes of a given division. Combination pistons are used to make rapid stop changes from the console on organs with electric stop action. Toe studs are pistons that can be operated by the feet which change either the pedal stops or the entire organ.

In some organs, a "pedalboard check" mechanism is used as a safety catch, to shut off the pedalboard keys when it is engaged. The mechanism prevents the pedalboard notes from being accidentally sounded during a part of a performance which is only written for the upper manuals.

Because this non-legato technique involves no sliding, shoes with leather soles are not required.

The Hammond organ is an electric organ invented by Laurens Hammond in 1934 and manufactured by the Hammond Organ Company. While the Hammond organ was originally sold to churches as a lower-cost alternative to the wind-driven pipe organ, in the 1960s and 1970s it became a standard keyboard...

 in jazz in the 1950s, many jazz pianists "... who thought that getting organ-ized would be a snap ..." realized that the Hammond "... B-3 required not only a strong left hand, but studied coordination on the foot pedals to create the strong and solid "jazz bass" feel." Jazz organists from more recent decades typically perform the bass line with their left hand on one of the keyboards, rather than by using the pedalboard. Organists who play the bassline on the lower manual may do short taps on the bass pedals – often on the tonic

 of a tune's key and in the lowest register of the pedalboard – to simulate the low, resonant sound of a plucked upright bass string.

In popular music, the pedaling style may be more varied and idiosyncratic, in part because jazz or pop organists may be self-taught. As well, the pedaling styles may differ due to the design of electromechanical organs and spinet organs, many of which have shorter pedalboards that are designed to be played primarily with the left foot, so that the right foot can control a volume (swell) pedal.

) and fusion bands have used bass pedalboards to produce sounds in the bass range. They are most commonly used by keyboard players as an adjunct to keyboards, but can be played in combination with other instruments (e.g., by the bass guitar or electric guitar player), or by themselves.

Standalone pedalboards usually have a 13-note range and short pedals, which limits the types of basslines which can be performed to fairly simple passages. If the group's bass guitarist or electric guitarist is playing the pedalboard from a standing position, they could only use one foot at a time to play, which would further limit the types of passages which could be performed.

, the pedals are not limited to traditional bass notes but may instead produce many different types of sounds, including high-register tones. MIDI pedalboards offer a range of features, depending on the price. Some MIDI pedalboards contain velocity-sensitive triggers, which allows a performer to use dynamics in their performance. MIDI pedalboards such as the 13-note Roland PK-5 include a row of MIDI toe switches above the pedal keyboard, to allow the performer to select preset tones or channels. Larger 25-note Roland pedalboards also include an expression pedal for controlling the volume or other parameters.

Some MIDI pedalboards are designed for the church pipe organ market, which means that they use AGO specifications such as a 32-note range. Most pipe organ-style MIDI pedalboards are too unwieldy for transportation, so they are typically installed under the upper manuals. However, a German company makes a MIDI pedalboard which has a hinge in the middle and wheels on the underside, which allows it to be moved more easily. Since AGO-specification MIDI pedalboards are often priced in between $1000 and $3000 USD, some amateur home organists make DIY MIDI pedalboards by retrofitting an old pedalboard with MIDI.
