Persichetti Exercise 2 - 56 for Clarinet Duo

I come to you with yet another piece prompted by an exercise from Persichetti's "20th Century Harmony" - Chapter 2:  Scale Materials.  This time the prompt was "11.  Extend the following polymodal and polytonal passage."

I chose to change the instrumentation to Bass Clarinet and Sopranino Clarinet as I thought that increasing the distance between the voices would preserve their individuality.  I also heard the bottom voice as being more in C dorian rather than in G aeolian.  But for the end of the piece I defaulted to a kind of linear cadence rather than ending each voice on its individual tonic.  Thanks for listening and I hope you enjoy and let me know what you think!

Huh, those two different scales together remain dissonant, even after listening several times.

Interestingly, while you separated the two voices clearly, for me the base clarinet „shadows“ the lydian fourth in the soprano, so that its characteristic is not so clearly perceptible.

I was just a bit confused whether the score/recording is transposing or not. I think, the score should be read „as is“ since the scales (B lydian vs. G aeolian) are explicitly mentioned in the exercise. But whenever I listen to the recording, I think the clarinets are playing a whole note lower, thus are transposing ...

However, very interesting exercise – while I would prefer a slightly more harmonic approach in my own compositions.
