I think he meant to type "harmonicas."
Anyhow, I'm adept at guitar, which is really all you need to play folk music. I'm also pretty good at harmonica, just need a better set than these plastic beginners. I play drums alright, so I'll throw that in, too.
With banjo and piano, I know chords and can play the same stuff I can on guitar and more...
And then there's stuff I just kinda mess around with. I had a bodhran, but it broke after someone beat it too hard... I have various odd things: tin whistle, toy accordion, etc.
Well, I think that's pretty good for me being just a kid.
