I have been playing on a Denis Wick Heritage 3 mouthpiece since March 2009 but was recently told I'm too bright. I thought maybe I'm just having one of those days, but then I thought it could be to do with not doing enough exercises on tone quality recently, even though I was told it'll be the mouthpiece by some people. I've decided that either way, it might be for the best to change, as I struggle with intonation on it and I found double and triple tounging easier when I tried a yamaha for 5 minutes a few weeks ago. Also, I've never really had as good a tone out of it as yamaha mouthpieces. I played on a Yamaha 16E and and lewington McCann mouthpieces a while back, but found the rim (which is flat at the edge) was cutting in below my bottom lip (because I play down slightly, because of the shape of my teeth, becasue of my jaw). Does anyone have any suggestions!!! I need something with a dark tone, that isn't stupidly deep (becuase I play front row in a champianship section band and my range isn't amazing), that isn't hard intonation wise, thats rim rounds off towards the outside so it doesn't cut me and that has a cup diameter of at least 16.75mm..........sounds hard to find!!!! Any advice/ suggestions are very welcome!! Thankyou!!
