Easley Blackwood - 13 notes Sostenuto

from composer: “13 notes: The most alien tuning of all: so disso­nant that no three-note combination sounds like a major or minor triad. Yet even this tuning contains a strange mode best described as “sub-minor.“ The first four bars of the Etude are an arrangement of this mode into consecutive thirds — a motif that recurs later in two trans­posed variations. The rest of the piece is com­prised of chromatic resolutions of complex altered chords.“ - Easley Blackwood from 12 Microtonal Etudes, Op. 28
