I only play the kazoo (in private in front of consenting adults only). I can pedal the player-piano and sing along but fail to play it. Other instruments I fail to play are a couple of harmonicas and a five-string banjo: my attempts at self teaching convinced me I have a tin ear (I already knew about the lack of hand-eye coordination!)no doubt why my spouse won't let me whistle (more off-key than my singing).
I should have stuck to playing on the linoleum.:)
When I retire in about 5 years time I WILL learn to play something, I WILL, I WILL.(Otherwise she'll get me doing the garden).
