Hi David, A thought, if we need the brightness due to the hall why not just transpose everything up a half step. <G> Joe Goss imatunr@primenet.com http://www.primenet.com/~imatunr/ ----- Original Message ----- From: "David Renaud" <studiorenaud@qc.aibn.com> To: <pianotech@ptg.org> Sent: Sunday, March 04, 2001 11:02 PM Subject: Re: Pitch and brightness > Perhaps I may offer some experience with this creepy pitch problem. > I am a woodwind player, Clarinets as major, saxes and flutes as minor. > I have played pops concerts with a national orchestra, > and much freelance pit work, the odd pick up orchestra. > > I can not explain the science, but I can offer my personal experience > that higher pitch is brighter.
