Hans, Either you have misremembered what they taught--physics is not your fach or specialty, or they mistaught you. Sound frequency does not change with distance from the source. If you are playing a 440 A, you are emitting 440 pulses per second. Far away those pulses don't get lost, and there are still 440 per second. There are theories that light does get "tired" after billions of years in addition to the Doppler effect of the receding galaxies, but we're not in that arena.
The effect may indeed be psychological. Timbre does affect the perception of pitch. If anything, when you are playing on a hot stage, I would expect you to play sharp. So much for theory... Question: Do the onstage players sound flat to themselves, or is it that they sound flat to the audience?

But how should this affect the intonation ? 440 remains 440, no matter what kind of curtain or deco they use on stage. Higher harmonics have nothing to do with that problem. But the distance effects (lowers) the intonation of a given pitch. We all learned that in school (classic gymnasium, physics classes) which seem to be abandoned in a greater percentage of schools. ############################################# Am 29.05.2011 um 19:47 schrieb Dan Beeker: > Surely there must be more to it than "because of the distance".
