Abstract: A musical instrument is disclosed which is constructed of a group of taut strings arranged to be strummed, each string being connected to operate an analog switch capable of producing a graduated signal that is directly proportional to the amplitude of vibration of its string, an extrinsic sound source in circuit with each analog switch, the sound source having a variable volume which is varied directly proportional to the strength of the signal from the analog switch, a number of switch means arranged in a keyboard, each of which may close the circuit to one or more preselected sound sources for which the switch means are closed and the strings are vibrating.
