Does anyone know of a resource which studies the differences in sound perception between musical keys (book/website/magazine article?)
As a practical example of what I mean: I want to inject more energy into a song that my band is playing. We've wound up the pace a bit. We've given the bass and drums a more repetitive doubling up of their rhythms, and inverted the chords... but I got to thinking, "What if we changed it to A major, or B major, or F#major?"
Is there any formula to how the difference in key would sound? Is it dependent on the instruments and how much of their strings/tubing is resonating?
