Well, I delved into my library of works when I was youngher and came across this one that I wrote for my brother (clarinet player) and his wife (piano accompanist). He performed it in 1979 (now I really am dating myself!) I realized it (it is an alleatoric score, so I wrote it the way I would have played if I could play clarinet.) It uses multi-phonics which sound much better in Garritan's library than in real performance. It's a whimsical piece but tough to take if you do not like this style of atonalism (clusters not chords, idioms not melodies - though there is the hint of melody and harmony in it to help hold it all together.)
Pleas do not throw objects at me after listening - you have been warned!!!!
