Aside form the Human voice...

The guitar can do everything the piano can...and more.

Not really, the freq range that a piano can cover is much wider than guitar.

If only the piano had a wind controller on it ... In lieu of that I would say the voice, then most wind instruments like sax and oboe and such, then a tie between piano and other stringed instruments.

It still takes a human touch to make real music (thank God).

Enjoy,

Guitar can't play 10 notes at once, can't....on and on...doesn't mean it's not more expressive, but it is more limited. I vote Piano.

Hell, if it's the number of notes and different voices at once that you want, how about the organ? In the right hands (and feet) it can be very expressive. I still vote for the cello, though.

I think it's down to the musician, not the instrument.

Most wind instruments can't be polyphonic, and most stringed instruments (and I'm including piano) can't be anywhere near as expressive on simple music as a wind instrument.
