Claude Fable 5.2 on the Bach Benchmark. One of the best chorales we’ve seen yet. This is the first time I remember seeing a third-inversion chord (m. 2) on this benchmark. There’s still a little awkwardness, such as the tenor doubling the third of the tonic in m. 9, but otherwise this is good solid work.
Prompt: “In LilyPond (version 2.24), write a 4-part chorale in the style of Bach, 3/4 time, G minor. Use two staves -- soprano and alto on the top staff, tenor and bass on the bottom staff. Respond with only the code block.” (Extra High effort)
