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
