Sorry if this is a duplicate thread... I'm curious how many trumpet players here believe that the way you hold your trumpet has an effect on your quality of tone. Yesterday I was practising some Arban interval exercises. I had quite a fuzzy sound and so was going really slowly, trying to make sure I really hit the centre of every note. At the same time as doing this I was thinking about a forum post I once read. I don't know if it was on TrumpetMaster or THat website. It was about how many people believe that having a leather valve-block protector on your horn can ruin resonance. Now I don't have anything strapped to my trumpet (just so we're clear), but I began thinking about where my hand was placed and if minimising contact with the horn would make any difference to my tone. I did some experiments and to my surprise it did. I found that if I try not to make contact with the leadpipe, where the tube then enters the valves, or where any part of the bell then my sound it much brassier and articulate than normal. So, how do you hold your trumpet? have you ever noticed a change in sound as a result? Any other related suggestions?
