Hi William you wroteYes, Marshall, the pitch of a piano does go sharp when the temperature rises, or goes flat when the temperature drops. You understand, of course, only if the temperature in the room in which the piano is goes up or down. The pitch also goes up or down depending on the humidity level in the room. Yes this is basic. I was commenting on this because someone posted if I read correctly that the pitch goes down when the temp goes up. Unless I was reading incorrectly. So no I'm not asking this as a question of course, I'm just commenting on what I believe I read in a post on here. Marshall Isn't this something sort of basic that your learned in school? So why do you ask? Marshall Gisondi MARSHALL'S PIANO SERVICE 215-510-9400 http://www.phillytuner.com -------------- next part -------------- An HTML attachment was scrubbed...
