  • G10H 2220/171 using electrified strings, e.g. strings carrying coded or AC signals for transducing, sustain, fret length or fingering detection
  • G10H 2220/175 using nonmagnetic string materials, e.g. nylon; Sensors specially adapted therefor
  • G10H 2220/181 by nonresonant wave interaction, i.e. string sensing using wavelengths unrelated to string resonant wavelengths, e.g. ultrasonic waves, microwave or light waves, propagated along a musical instrument string to measure its fret length, e.g. for MIDI transcription
