For Brass Ensemble and Choir

and don't they sound good.........

Very cool mate.

one could make any brass instrument to play in any temperament by valve placement and tubing length as far as I know. On the other hand 24 note per octave (and finer divisions) are avalable on wodwind and brass with using alternate fingering. On a recent trip to Urbana for a performance Peter's composition called for french horn playing in harmonic series tuning - but I guess the actual use comes close to 72 equal. The video of that is here: (go to about 16:40 .) http://www.youtube.com/user/clones98#p/u/30/OjY4LwBV8sM
