Read the question Which sounds more beautiful, and by guitar, I obviously mean acoustic I realize they are both beatiful intruments and it depends on the artist, but what sounds better to you. Don't flame or anything in here When you vote, reply, or I will be mad =]
I prefer the guitar more than the piano. Even though you said "More Beautiful", the guitar can be used in mulitple ways
Guitar all the way. Classical or Flamenco. Nice spanish licks can be soo soothing, and beatiful to listen too.
Tie for me... but I lean towards guitar because of the metal fan that I am and I can't stand the piano....
oh my god! raw sewage > flute. But yes, piano is THE most beautiful instrument known to man, besides the Cello, if played right.
