A couple of years ago as part of the strategy of playing with reduced mouthpiece pressure, I loosened up the grip of both hands and held my right hand little finger up out of the pinkie hook. So far so good.
Two years on and I've got on to finger flexibility exercises out of the Vizzutti method. Full works playing against the metronome, really bashing those valves down like billy-o.
Problem is that this finger pummelling is making the instrument bounce around a bit. If I put the little finger back in the pinkie hook, that works fine when 3rd valve isn't in play. But when it is, then it's out of the hook again to get some dexterity into the 3rd finger.
Gently resting the little finger on, rather than in the hook might end up being a workable compromise. Dunno.
Any thoughts, past lessons learned etc?
