Abstract: A detection system is provided for detecting a musical note played on a string instrument having a fretboard provided with a plurality of conductive frets and conductive strings. The system includes at least one conductor coupled to each of the frets; an inverter having a first terminal coupled to the conductor and a second terminal coupled to the conductive string, the inverter being configured to logically invert a signal transmitted therethrough, such that when the conductive string is pressed against one of the frets allowing thereby for a signal to be transmitted therethrough, the signal is sequentially inverted between two logical states at a frequency being dependent on the distance between the inverter and the fret; a frequency detector configured to measure the frequency; and a controller configured for determining the location of the fret along the fretboard in accordance with the frequency, and to thereby detect the musical note.

Abstract: A string instrument is provided having: a body with a sound hole; a neck extending from the body; a plurality of strings strung over the neck and sound hole; a plurality of frets positioned under the strings along the neck, a plurality of sensors positioned on the neck; and electronic circuitry associated with the sensors; characterized, in that each of the frets comprises separate individual fret sections each mounted over a corresponding sensor, thereby forming separate individual dynamic fret-activated sensors, each individual dynamic fret-activated sensor being positioned correspondingly under one of the plurality of strings. When a chord is played by applying finger pressure on the strings, pressure is applied on the corresponding individual frets activating the individual dynamic fret-activated sensors, which transmit the pressure data representing the played chord, via the electronic circuitry to a processor to produce an audio output comprising the played chord.
