Interactive exploration Physics, Light & Sound Guitar strings, musical notes, harmonics and resonance How does a guitar string make a musical note? Pluck a guitar, move a fret and hear the model. Pull a note apart into harmonics, investigate resonance, and open the instrument beside real research photographs.
