Here's a theory question, probably with not a lot of practical use. Last week it was very hot. I was playing in a saxophone group and I had my mouthpiece pulled out a bit further than usual in order to play at concert 440. I was wondering if all sizes of saxophone go sharp by the same amount when it gets hotter. So if we had all left our mouthpieces in their "usual" positions, would we have played in tune as a group? (Assuming that we can ever play in tune as a group and that there are only saxophones.) Someone in the group said that in her experience, tenor saxes seem to be worse than the others when it gets hot, but I don't know why that should be.
