Seeing Music in Colour: The Physics of Guitar Strings

Each wall of the corridor represents a voice in Pachelbel's Canon in D.

The walls of made of beams that correspond in length to the exact length of the guitar strings needed to each note. The beams light up when their pitch sounds.

The beams of the bass voice (Left) correspond to the various lengths of the low E String (tuned to drop D). The beams of the other three walls all correspond to the lengths of the B String.

We have used four different guitars to make the 4 voices of the Canon as distinct as possible.

Try focussing in on one voice at a time - maybe even singing or playing along!
