Data visualized as art, art visualized via data. This is what Martin Wattenberg does with music. Wattenberg created a visualization method called an “arc diagram” that highlights repeated sections of music–or of any audio sequence–with translucent arcs tat represents the audio waveforms.
On his website there are a number of these images that range from classical classics like Vivaldi’s Four Seasons, to modern classics like The Talking Heads “And She Was”. The images are quite beautiful, and if you would like to read either a complex or simple explanation of his work, click here. Oh and if you are really ambitious, you can upload a MIDI file and have him run it through the process here.
