I am actually posing a serious question, this isnt a wind up. I have been getting frustrated recently with my playing, and one aspect in particular. In very fast pieces/ solos during my practice (Carnival of Venice for example) i am struggling synching my fingers and lips. Up to a certain speed my fingers keep pace with what my mouth is doing, but when i up the speed to my limits, my fingers cant keep up! im constantly fluffing notes because the valve isnt fully depressed when i tongue the note. My Question is, being left handed am i at a disadvantage having to use my 'bad' hand for the valves? after maybe twenty minutes of playing fast stuff i have to stop because my tendons ache so bad in my right hand. Do other left handed players have a similar problem, or is it just me? If you have tried writing a sentence with your left hand (if you are right handed) then you will know how different it feels to use your wrong hand to do stuff, I cant help feeling i would be better at coordinating a really fast piece if i was right handed?
