If you do find yourself at a session where there's a lot of bodhrans, make a point of learning to play to polkas. A lot of drummers can't play them so at least you'll get a fair share of playing. (And they're a lot of fun once you get the hang of them). In slipjigs try not to cheat them. Play the alternate measures starting on an upstroke. It really adds to the feel of them. Play them gently and pretty (Yes a bodhran can be played pretty!) If you have a hard time with them a good one to start with is Barney Brallaghan. If the rhythm starts to throw you, the C part will help you get it back. Likewise, a good polka to learn bodhran on is Jer the Rigger.

All the best,

Rich
