Abstract

Abstract The `Tonal Exponent` is a mechanical device which clamps onto the neck of a stringed musical instrument and allows one or more of the instrument's strings to be selected and mechanically depressed and held-down throughout a song or a portion of a song. The notes and chords thus produced span a far greater lateral distance than the human hand is capable of stretching, and open up a whole new spectrum of possible chord and string sounds. A unique new recurring rhythmic element, `constancy within change, ` is also introduced by use of the device, giving an invariable yet subtle syncopation to those strings engaged while allowing the musician to manipulate the other strings as he or she desires. A wide new range of atonal, microtonal, and polytonal musical explorations are made possible by use of the device.
