quadrpitch
Quadpitch is a type of musical instrument that combines the features of a guitar and a piano. It was invented by John McLaughlin, a British jazz fusion guitarist, in the late 1960s. The instrument consists of a guitar body with a piano-style keyboard attached to the top. The keyboard has 61 keys, covering four octaves, and is played with the right hand, while the left hand plays the guitar strings. The quadpitch is tuned to the same pitch as a piano, allowing for a wide range of musical possibilities. It is often used in jazz, fusion, and rock music, and has been played by several notable musicians, including McLaughlin himself, Pat Metheny, and John Abercrombie. The instrument's unique sound and versatility have made it a popular choice among musicians looking to expand their sonic palette.
