The Music Animation Machine is a tool for visualizing music in new ways using video and computer formats. It helps the listener to understand the music in an intuitive way by displaying a scrolling animation of coloured bars that light up on the screen as the music plays.
Here’s a description from the site.
"The Music Animation Machine display is a score without any measures or clefs, in which information about the music’s structure is conveyed with bars of colour representing the notes. These bars scroll across the screen as the music plays. Their position on the screen tells you their pitch and their timing in relation to each other. Different colours denote different instruments or voices, thematic material, or tonality. And each note lights up at the exact moment it sounds, so you can’t lose your place."
The M.A.M. project has been around since the 1980s and the DOS software is offered free to anyone interested.
