Imagine a diminished seventh chord (say C Eb F# and A) and then join the notes with passing notes. The result is the tone/semitone octatonic scale - so there are hints in both Mozart + Beethoven. Liszt developed it and then Rimsky-Korsakov. And then . . . well here's a quote from the Felix Petyrek thread (20th century) which mentions a few other composers
Of particular interest is that [Petyrek's] Third Sonata (and other works?) seems to mark him out as a serious Mode 2 merchant, in common with several fascinating composers of that time or just before/after it. I'm thinking not only of such as Ravel and Stravinsky (not Debussy, despite Allan Forte's attempts to convince the world otherwise), but also Lili Boulanger, Protopopov, Ornstein, Frank Martin, Bloch (of the 1st violin sonata), Schulhoff (e.g., piano concerto), Pijper - let alone Scriabin (if one can ignore Dernova's theories for the moment) and various Russian followers - and no doubt a few others whom I've forgotten. I seem to remember a reference to this scale in Nicolas Slonimsky's Music since 1900 where he mentions Pijper, Petyrek and Ludomir Rogowski - not heard a note of this last composer: has anyone else?
So there's a considerable prehistory. Some composers since have based entire pieces on just one version of the scale, notably Lou Harrison (middle movement of
Double concerto for violin, cello and Javanese gamelan and the 2nd movement of the
Grand Duo for violin and piano).
Here's the
Grand Duo example - oh, and there's lots of additional clustery stuff in the piano part produced by the pianist using an implement akin to a blackboard rubber.
