Thanks, PeterT and Dave el Swanno! As long as we're quoting the Bard re' music, how's this one (Oh...and Peter, I thought you were giving up Saturdays at work!):

Orpheus with his lute made trees,
And the mountain-tops that freeze,
Bow themselves when he did sing:
To his music plants and flowers
Ever sprung; as sun and showers
There had made a lasting spring.

Everything that heard him play<
Even the billows of the sea,
Hung their heads, and then lay by,
In sweet music is such art,
Killing care and grief of heart
Fall asleep, or hearing die. Henry VIII
