The Chapman Stick is an electric musical instrument devised by Emmett Chapman in the early 1970s. A member of the guitar family, the Chapman Stick usually has ten or twelve individually tuned strings and is used to play bass lines, melody lines, chords, or textures. Designed as a fully polyphonic chordal instrument, it can also cover several of these musical parts simultaneously.
