Let's see...I'm fairly proficient on the accordian (don't laugh, I'm not joking!). I also play the harmonica (awesome blues instrument), a little guitar, and I played the trombone once upon a time.
But how, my dears, can you call the piano BORING!?! It is still, hands down, the most versitile instrument around. Nothing else compares to its versatility of dynamic and style! I simply cannot understand how you could be bored at the helm of this instrument...!?!
