Claude writes a Bach-style organ fugue in LilyPond with a single prompt

IgorCarron · x · 2026-11-12

User aug5thmusic prompted Claude Fable 5.2 (Extra High effort) to write a complete organ fugue in the style of Bach using LilyPond 2.24 notation, calling the result good though not better than Opus 5.5. IgorCarron shared it with "And they fall...", implying classical composition is falling to AI. The prompt technique—asking for a full polyphonic work in professional notation—is reproducible.
