The Autocorrelation of Music

The search that you're doing on the music is looking for parts of the music that are similar. Is it analogous to a beat detection kind of approach or something different? It is related to that. The other setup is where you have different people coming and drawing these different strokes. And what we found there is that these sketches look entirely different. They, they qualitative look very different from what happens when one person draws it all out.
