Progressive tonality
Encyclopedia
Progressive tonality is the name given to the compositional practice whereby a piece of music does not finish in the key
Key (music)
In music theory, the term key is used in many different and sometimes contradictory ways. A common use is to speak of music as being "in" a specific key, such as in the key of C major or in the key of F-sharp. Sometimes the terms "major" or "minor" are appended, as in the key of A minor or in the...

Tonic (music)
In music, the tonic is the first scale degree of the diatonic scale and the tonal center or final resolution tone. The triad formed on the tonic note, the tonic chord, is thus the most significant chord...

Musical mode
In the theory of Western music since the ninth century, mode generally refers to a type of scale. This usage, still the most common in recent years, reflects a tradition dating to the middle ages, itself inspired by the theory of ancient Greek music.The word encompasses several additional...

: Mahler's 2nd Symphony
Symphony No. 2 (Mahler)
The Symphony No. 2 by Gustav Mahler, known as the Resurrection, was written between 1888 and 1894, and first performed in 1895. Apart from the Eighth Symphony, this symphony was Mahler's most popular and successful work during his lifetime. It is his first major work that would eventually mark his...

A work which ends in the key in which it began may be described as exhibiting 'concentric tonality'. The terms 'progressive' and 'concentric' were both introduced into musicology

, did composers feel compelled to end even individual operatic acts and scenes in the starting key. Single operatic 'numbers' which (usually for some discernible dramatic and expressive purpose) fail to return to their original tonics can also be found—while in the quartets, symphonies and sonatas of the time such a practise was exceedingly uncommon.

As in his symphonies, Mahler took the idea of 'progressive tonality' in the song cycle to an extreme of refinement: each of his four Lieder eines fahrenden Gesellen

's concept of the 'background' Ursatz (fundamental structure), rooted as it is in a metaphysically elaborated appreciation of the acoustic resonance of a single tone, inclines towards a severely monotonal approach to musical structure: either the opening or the closing key of a progressive tonal structure will frequently not be considered to be a true tonic. By contrast, Graham George

 developed a theory of 'interlocking tonal structures', in which two tonal 'axes' could coexist, with the second emerging after the first was established, and persisting after it was abandoned. Later generations of Schenkerians, following Harald Krebs have begun to identify "background conglomerates" in works that permanently change tonics: in this approach, two fundamental structures (Ursätze) are held to be present in the background of such works, one of them being the so-called elided fundamental structure (Ursatz).

The tonal workings of these symphonies were analysed with particular clarity by the British composer and writer Robert Simpson
