[harmonica - just chords / clarinet - just single notes / violin - only "implied" chords (a true chord is a triad...three notes, but because of the way the strings of a violin are arched, it's impossible to play more than two notes at a time - so you play the two and add the third note a bit afterwards - not an actual chord, but an "implied" chord)]
so, piano covers the most ground as far as i can tell. the only thing i can think of that it doesn't do is.....bend notes / vibrato.
as a side note, have you ever heard that Billy Joel can play so hard that he used to break PIANO strings on the regular ? that's what he said.
