ABSTRACT:
Disclosed is an electronic musical instrument resembling a guitar that is played like a guitar and sounds like a guitar; however, it is stringless and has a plurality of flexible actuator blade type members which are mounted on edge and are adapted to be strummed or picked. Flexing of each actuator blade in either direction closes one or more leaf type switches which controls the amplified output of an electronic oscillator whose fundamental operating frequency is further varied in accordance with finger actuation of a plurality of fret-board switches. Although the invention in its preferred embodiment is directed to a guitar-like instrument, it is also applicable to other types and classes of musical string instruments such as a violin.
