<p>An electronic stringed musical instrument having an electrically insulating fingerboard is disclosed. The fingerboard is provided with a number of segmented frets attached across its upper surface at desired points along its length. Each of the frets includes a number of electrically conducting fret segments each of which are electrically insulated from one another. Any number of strings may be provided on the instrument each string is disposed adjacent to and associated with a single fret segment of each of the segmented frets. A top-octave generator and octave dividers are utilized to selectively provide a fret segment of one of the frets with an electrical signal of at least one known referencing frequency. The strings are attached to the instrument in a spaced relationship with respect to the fret segments. Displacing a string to contact one of the fret segments completes an electrical circuit having at least one frequency equal to a frequency of the signal provided to that fret segment. Displacing the same string to contact a different fret segment completes a different electrical circuit having at least one different frequency. Simultaneously depressing a plurality of the strings simulataneously completes a number of electrical circuits each capable of producing a number of different frequencies. The amplitude output of the instrument is dependent upon the voltage applied to each of the strings and is controlled by hand operated transducers.</p> |
