There's been a little bit of discussion of the effect of weather conditions on drums. What about temperature and cymbal sounds? I can't put any objective measure on it, but 1960s 20" and 21" Zildjian crashrides I have do both seem to sound nicer when it's warm. Similar seems to be true of my 22" Bosphorus Traditional ride and 20" Bosphorus Jeff Hamilton signature ride.
I can't decide whether it's the way I am when it's warm, or whether it's the cymbals. Has anyone looked into this more scientifically?
