Musical instruments are described including a first portion designed to be operated by one hand of a player and a second portion designed to be operated by the other hand. The two portions include means within each for sensing hand and/or finger activity, position or movement, and one of the portions is adapted to produce an output signal corresponding to the music being played by the user. The two portions may be physically connected together or they may be separate, each including its own power supply to enable it to operate, and for the two portions to communicate with one another. The invention is of particular value in the construction of practice instruments which do not need to include a sound box, and can thus be very compact, especially if the two parts, such as a fingerboard (20) and a body (82) with strings (83) mounted on it are connected by a telescopic neck (60A). |
