No other acoustic instrument can match the piano's expressive range, and no electric instrument can match its mystery.
— Kenneth Miller

If you can't play it on an acoustic guitar or a grand piano then it's not a song.
Christopher Cross acoustic quote

I prefer to sing in the shower 'cause the acoustics are really, really good, I mean, when you're singing against the tile walls then you really hear yourself, hear your voice, you know, throwing itself back at you.
— Thia Megia

I prefer to sing in the shower because the acoustics make you sound great, baby.
— Naima Adedapo

The classical guitar has a dynamic to it unlike a regular acoustic guitar or an electric guitar. You know, there's times when you should play and there's times when you gotta hold back. It's an extremely dynamic instrument.
— acoustic quotation by Steve Vai
