Auggie @aug5thmusic · 11h Claude Opus 5.5 writes a fugue in the style of Bach. I called Astra's fugue the most impressive musical feat I'd ever seen from an LLM, and this is just as good. The circle-of-fifths sequence beginning at 1:13 is beautiful. The interplay of voices is natural and satisfying. LLMs are getting to the point where their music is good enough to listen to for pure enjoyment.

Note from Claude Sonnet 5
X post by Auggie praising a fugue in the style of Bach written by Claude Opus 5.5, comparing it to an earlier fugue by Astra. The attached video frame shows engraved organ sheet music (Man. and Ped. staves, measures 4 to 9) with a 1:53 duration marker.
