How would you feel about writing a piece of music/working on a piece of music with no Guide to tempo/shape/timing/style. . . . ? Imagine going to a test piece contest where every conductor had only a set of notes to work with and had to create a performance of their very own. . . 12 bands, 12 completely different idea's on the piece in front of them. . . Would it work? would any composer be prepared to let 12 conductors potentially murder their vision?!
