A fretless banjo player the other evening had a neat little trick he did as part of playing "Cluck Old Hen" - a high up the neck lick that sounded like a chicken clucking.

It got me to thinking about all the special effects that can be done with various instruments: 12th fret harmonic chimes on guitar or banjo as clock ticking sounds on "Grandfather's Clock" - string plucking with the left hand on fiddle in "Pop Goes the Weasel" and other tunes - crossing the low strings on guitar to achieve a snare drum sound for marching songs - doing bird imitations on the fiddle for "Listen to the Mocking Bird," etc.

What are the musical tricks that you do or have seen done, and with which songs??
