Abstract

A harp comprising a body, a set of strings attached to the body, an optical pickup to generate an analog signal produced by the vibration of a string within the set of strings, at least one circuit board to convert the analog signals to a corresponding digital signal, wherein the digital signal is then processed.

Claims

1. A harp comprising:

a body;

a set of strings attached to the body;

an optical pickup to generate an analog signal produced by the vibration of a string within the set of strings;

at least one circuit board to convert the analog signals to a corresponding digital signal;

wherein the digital signal is then processed.

2. The harp of claim 1 the set of strings are lighted.

3. The harp of claim 2 wherein the set of strings at a lower audio spectrum are lighted with lights in a low end of the visual light spectrum.

4. The harp of claim 2 wherein the set of strings at a higher audio spectrum are lighted with lights in a high end of the visual light spectrum.

5. The harp of claim 1 further including a set of circuit boards.

6. The harp of claim 5 wherein one of the set of circuit boards is for analog to digital conversion.

7. The harp of claim 5 wherein one of the set of circuit boards is for a computer interface circuit.

8. The harp of claim 5 wherein one of the set of circuit boards is for a string light control circuit.

9. The harp of claim 5 wherein one of the set of circuit boards is for a light emitting diode (LED) control circuit.

10. The harp of claim 7 wherein the computer interface circuit receives signals from and transmits signals to a processor for controlling the harp.

11. The harp of claim 10 wherein the signals are Musical Instrument Digital Interface (MIDI) signals.

12. The harp of claim 1 further comprising a pedal for controlling the set of strings.
