Just wondering really - I know many sax/clarinet players use a different mouthpiece/reed setup for playing jazz as opposed to classical. Is the same true for the flute? I'd welcome opinions on whether a different headjoint cut makes a significant difference to the character of the flute (I know it affects the tone and ease of blowing)? Is there a specific cut that certain types of players favour?

Some professional doublers prefer certain makes, as they think they are easier to play as doublers - but with flute, so much depends on the player that I would have thought any decent make would be flexible enough.

Mind you, the range of tone that jazz players use also suggest to me that there is no distinctive style of 'jazz' saxophone mouthpiece. The best one can say is that certain mpcs (e.g. Runyons, Guardalas, Bergs) are probably going to do you no favours in a classical setting! Mainstream pieces (mid-lay yamahas, selmers, yanis) are probably fine for most everything, except roaring rock music.
