ABSTRACT:
An electronic stringed instrument which uses electrical resistance wires as strings to control the frequency of electrically generated sounds. By shorting a string at various points along its length a variable voltage output is obtained and converted into a known frequency. A fretted instrument provides a means to incrementally control the voltage output and a non-fretted type instrument with a conducting fingerboard can provide a means to variably control the voltage output. A separate current source may be provided for each string to facilitate chord playing and a control for the intensity and harmonic content of the signals is provided. An internal power supply and speaker may also be employed to make the instrument readily portable.
