Great idea. After telling claude to "make a song" and pointing it to the strudel docs, it gave me this:

According to claude:

  It layers a pentatonic guitar melody with filter sweep, a saw/triangle bass, warm e-piano chords, TR-808 drums, and a sparse music box that drifts across the stereo field.

I'm blown away.

I do acknowledge the possiblity that it might be heavily plagiarized from an original composition in the training set - I wouldn't know.
