In collaboration with Japanese vocalist, Yantara Jiro, we imaged a short vocal melody to assess how quickly the CymaScope's water membrane is able to follow changes in the pitch of musical sounds. The water has a natural hysteresis, thus, it takes a finite time for the water molecules to take up new wavelet placements in response to a new set of imposed frequencies.
This effect can be seen during the moments of transition as Yantara changes his vocal pitch during progress of the melody. The color was added as an experiment in which each musical note was allocated with a specific color.
