Please listen to this. It is definitive and there is nothing to be gained by screwing with tunings.
Well...yes and no.
Again, it's not because music becomes any more "special," but because of timbral differences that result from pitch changes. That's why I think the study I quote above is flawed, because it changed frequency by pitch-shifting, not re-recording the music at a different pitch center. No one likes the sound down of a downward pitch-shift, right?
A lot of my opinions about tuning changed once I started working on the manual for G FORCE and had to test the various functions. For example I got into subtle tuning tweaks for individual strings, like basically doing the equivalent of a piano's "stretch" tuning on guitar ("sweetening"). But tuning down half steps and such does make a difference. It makes it easier to bend strings, too
Also, orchestras that tune to higher than 440 Hz do so because they believe the sound is sllghtly brighter. It's subtle, but apparently it's enough for conductors to be picky about it. Baroque ensembles often tuned way up, and orchestras had a period of "pitch inflation" during the 19th century where they kept tuning higher and higher to produce brighter timbres--I guess it was that period's equivalent of overcompressing
. It got totally out of hand when La Scala decided A was 451 Hz.
Higher tunings change the amplitude of the harmonics with strings. Maybe one reason why people think 432 makes a difference is because the tone is duller, so they find it more new agey. Or something.
