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!

Well!  That quite possibly might be the most interesting thing I've heard in a long time.  A very tricky thing to put together.  Myself, I've always found canons far more difficult to write effectively than fugues, so therefore I must commend you.  This is a very effective little piece.  

I must say, I don't much care for the sopranino clarinet up top, far too shrill, and I find myself wondering if the whole top part mightn't sound better on a regular B-flat clarinet an octave down.  I suppose the texture is more modern for it though as is, and therefore part of your plan.  

Great work!
