I was recently given a tin whistle as a gift. It's something I'd been interested in learning to play as a tiny step toward the (likely forlorn) hope that I might one day learn the Irish bagpipes.
As soon as I picked up the whistle and began to play, it felt most natural to have my right hand closest to the mouth. I am oddly-handed: I prefer my left hand for writing but do most other things with my right hand. I haven't had any problems so far playing this way round.
I now see that my tutor book - and a lot of advice online - say that the left hand should be on top, not the right. Some sources emphasize this very strongly, in one elevating to the status of the first "commandment" of whistle playing.
I've tried doing this and it feels clumsy and unnatural. A feeling that will ebb with practice, of course, but having to do the extra work on top of learning to read music and the finger skills themselves is terribly disheartening.
Is there any good reason why I should not keep playing with my right hand above the left?
