| Abstract: |
A sound enhancing apparatus for use with a string instrument has separate tone pick-ups for picking up the tones of individual strings and circuits for, determining the fundamental tones of these tones, multiplying the frequencies of these fundamental tones by small integers and/or dividing them by small integers and consequently producing harmonic overtones and/or undertones. The thus produced harmonic undertones and/or overtones are selected and amplified according to fixed and/or adjustable criteria and finally admixed with the original sound. The electronic apparatus for performing the process can operate in analog or digital manner.

First Claim:

I claim:
1. A method for enhancing the sound of a string instrument by extending the frequency range of the sound produced comprising the steps of
- detecting the fundamental tones produced by each of a plurality of strings of the instrument,
- electronically generating at least one overtone or undertone for each of the plurality of strings, each said overtone or undertone being a harmonic of the fundamental tone of its associated string, controlling the intensity and time pattern of each said harmonic overtone or undertone as a function of the intensity of the fundamental tone and of a predetermined priority logic, and
- mixing the controlled harmonic tones with the originally produced fundamental tones.
