Emmett Chapman, a jazz guitarist, invented the Chapman Stick in the early 1970s. This electric musical instrument, a member of the guitar family, typically features ten or twelve individually tuned strings and can be used to play bass lines, melody lines, chords, or textures. Unlike the traditional guitar, the Stick is played by tapping or fretting the strings, allowing for the production of multiple notes simultaneously. It is available with passive or active pickup modules and can also trigger synthesizers and send MIDI messages to electronic instruments. The Stick is held using a belt-hook and a shoulder strap, allowing both hands to naturally and comfortably address the fretboard. Notable musicians who have used the Chapman Stick include Alphonso Johnson, Tony Levin, and Amy Grant. The instrument has been featured in influential recordings such as the 1981 King Crimson album "Discipline" and Emmett Chapman's album "Parallel Galaxy." With its unique construction and versatile playing techniques, the Chapman Stick continues to captivate musicians and audiences alike with its innovative approach to music-making.
