Persichetti Exercise 2 - 14 for Clarinet Trio

This time I wrote a piece inspired by an exercise from Chapter 2 of Persichetti's "20th Century Harmony" on Scale Materials for 2 Bb Sopranino Clarinets and Bb Bass Clarinet.  The prompt was "14.  Construct a canon for three clarinets in which each performer plays a different synthetic scale on a different tonic."  Synthetic scales are scales that are "specially constructed, often non-traditional scales created by altering, adding, or omitting notes from standard diatonic (major/minor) scales."  I chose to use the written C Acoustic Scale, F Ukrainian Dorian Scale, and B Phrygian/Dorian Scale.  I've been told that I should have perhaps tried to choose scales that would sound more harmoniously with each other.  But, funny enough, that's exactly what I was trying to do.  I didn't choose scales at random but tried to tailor each part of the canon to the previous material by improvising a scale and only later figuring out what scale I was using.  But let me know what you think!  Thanks for listening!
