This is a well crafted Etude, Andreas. I didn't know that you composed music? It's tricky to maintain the 12-tone continuity throughout, but you maintain a good sense of form, which most "composers" lack these days. I admit I wasn't sure where you were going to go thematically, but the suspense was worth the wait. Now you need to follow it up with 1 or 2 more Etudes to make a nice little set.
Thanks for your encouraging words, George. Yes, the form-aspect is quite often neglected these days, though not by all composers. For me it´s indeed an important matter. I think, we are in a great and long occidental tradition of music and we have so many great types of form and traditional ideas we can play with in a new creative way. I think there are two groups of composers: those, who want threw away all tradition and those, who want continue it in a new way. I´m counting myself to the last group! (And I also think, Jürg Baur, my teacher, was one of the last group for sure.)
So, I see that you fell for the 3D craze?... Too bad I through away my 3D glasses. Keep up the composing!
I really wished to have more time for composing, but somehow my creativity through the last 22 years was concentrated more on the interpretation of music. I have composed quite a lot of pieces between 1981 and 1990. But thanks for your encouraging words!
