‘Resonant Chamber’ – Animusic. If you aren’t familiar with Animusic and their computer generated animated videos, consider yourself introduced. You can go to Youtube and search ‘animusic’ to see several other equally interesting videos. One of the interesting aspects is that the computer generation allows the video to display the precise notes, the exact notes, that correspond with the sound. The ‘fingers’ are not simply playing any notes in-sync with the music.. they are playing the correct notes in sync with the music. .
