Prelude and Fugue in A flat minor - (2012)
Diatonic triads yield to the inclusion of non-harmonic tones, becoming fully
polytonal as at measure 16. The "tenor voice" predominant in the midst of
the prelude becomes the fugue subject to follow.
fugue opens out of the final cadence, and as a stretto at the outset
with a third voice for harmonic content. Additional recurrences of the
subject occur beginning on other notes of the natural minor, including the
seventh as an emphasized color which also begins the prelude. The last
cadence retires into a lightly polytonal quiet.
