What is your favorite quote on music? Mine is I don't make music for eyes. I make music for ears.
Adele
Arthur Sullivan, in 1888, having seen a phonograph for the first time: "I can only say that I am astonished and somewhat terrified at the result of this evening's experiments: astonished at the wonderful power you have developed, and terrified at the thought that so much hideous and bad music may be put on record forever."
Simple and yet profound. Duke Ellington said "If it sounds good it is good."
