Here is the 2nd and final movement of my Octet for Winds and Percussion. It was very difficult to get the slides and glissandi accurately realized in Finale 2007. The piece is written in alleatoric style (non-measured and much of the performance left up to the performer's will).
Octet MM II
It's not for the faint of heart.
And, since I get the impression many do not know how to listen to this type of music, I have included the form outline below:
A INTRO - passing clusters with trilled 2nds to an oboe solo followed by a clarinet solo
A' Repeat - as above but clarinets have the original oboe solo material and the oboes conclude with the restatement of the clarinet solo material
B Woodwind susttained clusters with brass outbursts
A" to B' Woodwind moving clusters against the brass outbursts
A"' CODA - a chorale section for the woodwinds with the cluster acting like the last string section of Ive's "Unanswered Question"
the brass have one more outburst and then the trumpets have a quiet duet against the obstinate woodwinds.
The percussion are used to accenuate or "slap" the brass for all their naughty outbursts.
