This video presentation is an interesting comparison made between the patterns produced by certain pitches and frequencies in Cymatics and the symbols on the faces of the cubes. Tommy s assigned note of the pitch can be heard in the voices of the choir as it merges with the pitch of the cymatics demonstration. If you listen closely to the pitch of the oscillator (humming the pitch to yourself) you will hear the first note of the choir and its relevant cube, are the same.
