J. S. Bach's Sinfonia #4 in D minor, performed and visualized by Stephen Malinowski. FAQ
Q: What do all the shapes and stuff mean? A: The background shading shows how the measures are subdivided (with more important beat positions shown darker); the 3-dot groups are the beginning of the theme; the tapered bars show where notes are sustained across a beat ("suspended"); the chromatic motion which concludes the two main sections is shown with rolling boxes.
