    12 Piano notes made visible for the first time

    12 Piano notes made visible for the first time

    Shannon Novak, a New Zealand-born fine artist, commissioned us to image 12 piano notes as inspiration for a series of 12 musical canvases. We decided to image the notes in video mode because when we observed the 'A1' note we discovered, surprisingly, that the energy envelope changes over time as the string's harmonics mix in the piano's wooden bridge. Instead of the envelope being fairly stable, as we had imagined, the harmonics actually cause the CymaGlyphs to be wonderfully dynamic. Our ears can easily detect the changes in the harmonics and the CymaScope now reveals them--probably a first in acoustic physics.

    Capturing the dynamics was only possible with HD video but taming the dynamics of the piano's first strike, followed by the short plateau and long decay phase, was tricky. We achieved the result with the help of a professional audio compressor operating in real time.
