I snarfed some music related taglines, they have all sorts of eBonMots!

• Music: a complex organization of sounds that is set down by the composer, incorrectly interpreted by the conductor, who is ignored by the musicians, followed by the audience.
• 'Music is a moral law- it gives wings to the mind, A soul to the universe, Flight to the imagination, A charm to sadness, A life to everything.' -- Plato
• Never look at the trombones. You'll only encourage them. - Robert Strauss on conducting
• "There's nothing remarkable about it. All one has to do is hit the right keys at the right time and the instrument plays itself." - J. S. Bach
• "Music is the science of manipulating emotion through sound." - Angus Gray
• Anything too stupid to be said... is sung.
• "Writing about music is like dancing about architecture." - Thelonius Monk
• We're all pretty geeky people.... I think you'll find that your average rock star is a dork. - Adam Duritz of Counting Crows
• Music is the art of thinking with sounds.
• I'm a fermata - hold me.
• John Lennon --> ///o-o\\
• Jazz is not dead, it just smells funny. - Frank Zappa
• We don't like their sound, and guitar music is on the way out. --Decca Recording Company, on rejecting the Beatles in 1962
• "Somebody said to me, 'But the Beatles were anti-materialistic.' That's a huge myth. John and I literally used to sit down and say, 'Now, let's write a swimming pool.'" -Paul McCartney

• "Music washes from the soul the dust of everyday life." - Berthold Auerbach
• Due to the confusion from too many genres of music, we have decided to put both country music and rap music into the genre of Crap music.
• "New music is old music played twice as fast and half as well" - James Douglass Morrison
• These are bagpipes. I understand the inventor of the bagpipes was inspired when he saw a man carrying an indignant, asthmatic pig under his arm. Unfortunately, the man-made sound never equalled the purity the sound achieved by the pig. - Alfred Hitchcock
• 'You have to stick with it. Sometimes you are going to be so frustrated you want to give up the guitar. But all of this is just part of learning, because if you stick with it, you are going to be rewarded.' Jimi Hendrix, October 1968
• 'Some people crave baseball. I find this unfathomable, however, I do understand how someone could get excited about playing a basoon.' -Frank Zappa

Wincing Devil Disco is to music what Etch-A-Sketch is to art.
