Usually on guitar, it's "Music For A Found Harmonium," the riff from "Fly Like An Eagle" by Steve Miller Band, the bass line for Jim Croce's "Operator," "Prelude in A" by Weiss, or that section in "Carmina Burana" that's called, I think, "Dulcissimus."

On violin, it's always "Cripple Creek."

On whistle, it's usually "The Women of Ireland," "Song of the Pooka," or "Lullaby" from "Gayane" by Khachaturian.
