The same questions about form arise here.
Penderecki pushes the boundaries of musical form as he explores the boundary between music and noise.
At what point does noise become music and music noise? What is musical form?
This You Tube video is a perfect illustration: a 5.33 minute clip of the 9.13 minute Polymorphia. The last 27 seconds are vital to this illustration - as indeed are the preceding 5.07 minutes.
What is also illustrated in this clip is the extent of the musicians' creativity, as well as the composer's.
Quote from Penderecki:
"The problem for all composers, not only for me, is that we have to use instruments which were built 300 years ago, or 200 years ago. In the century of the great discovery, landing on the moon and so on, we still have to write for very old instruments, museum instruments, really. It became really the problem in the second half of the 20th century, that there is not much progress because of the lack of the instruments."
Using these traditional, conventional instruments, Penderecki probes the expanse of creativity with scores that ask his orchestra to use their 'tools' in unconventional ways, to push their own creativity to the limit to the same extent as he probes his.
Supreme creativity brought about by the exploration of form; form brought about by the exploration of creativity (the latter being contemporary form, as in 'of its time').
