Does anyone know anything about playing harmonica im interested in getting one just to play around on. What would be the best key of harmoica to buy?
#2
Get a diatonic harmonica (the one with 10 holes) in C major.

As for how to play, there are some nice tutorials on the 'net.
Dear God, do you actually answer prayers?

Yes, but only in a way indistinguishable from random luck or the result of your own efforts.

ive been looking at getting one myself, pretty much everywhere ive checked says to get one in the key of C, i think im gonna get a Hohner special 20 or a Lee Oskar major diatonic
No endeavour rivals science in its incremental progress towards a more complete understanding of the observable universe.

I've played both models and I myself prefer the Lee Oskar. They tell me it lasts longer too (takes longer for the reeds to go out of tune).
