You have between your legs the most sensitive Beerbohm instrument knowntoman, and all youcandoisscratch it.

-Beecham, SirThomas
Attributed rebuke to a female cellist. Quoted in Ian Crofton and Donald Fraser  A Dictionary of Musical Quotations (1985).

A tap at the pane, the quick sharp scratch And blue spurt of a lighted match, And a voice less loud, through its joys and fears, Than the two hearts beating each to each!

-Browning, Robert
  Dramatic Romances and Lyrics,'Meeting at Night'.

Engraving then, is, in brief terms, the Art of Scratch.
