I think I have stumbled on something. Distance has no effect on pitch, only relative motion does.
HOWEVER What the sound has to travel through before getting to the audience has a great deal to do with pitch. Air travels at different speeds through different mediums, so thick walls and thick stage matter could have a slight effect on when the sound arrives to the audience, and how. The temperature of the medium affects the pitch as well, so it's very well possible that the temperature off stage could be very different from on stage, due to hot lights, etc. Every time I can remember being under a stage or off stage, it was much colder than on stage. -William -----Original Message----- From: Curt Austin <[email protected]> To: debeeker <[email protected]>; The Horn List <[email protected]> Sent: Sun, May 29, 2011 1:58 pm Subject: Re: [Hornlist] offstage brass I didn't think frequency was affected by distance, and I've confirmed this with a little online research. A complex sound may sound lower since high frequencies are attenuated more, but this is an affect on timbre, not pitch. If there is a pitch difference, it could be position of the hand - if a horn player is standing offstage, he might alter is normal hand position in such a way that tends towards flat. Or it could be some psychological affect - something that makes us want to play lower pitches when away from the group. Maybe we figure we should sound more muffled, and jam our hands in the bell. Or we normally force ourselves up a bit without knowing it, but away from the group, we lose the connection, and go flat. Or the way onstage musicians perceive pitch "at a distance" could be the factor. Seemingly, an easy thing to investigate. Interesting.
