Fable 5.2 composes a 'mirror gigue' whose second half rotates the first by 180°
guillermosan · reddit · 2026-11-10
A Reddit user asked Fable 5.2 to continue a synth-baroque suite with zero guidance beyond the previous piece — and it produced a composition whose second half is the first rotated 180° (inverted and retrograde), with a published score visualizing the mirror structure.
Asked whether Bach did this, the model gave a knowledgeable answer: inversion was common in the Baroque era and retrograde rare, but rotating a whole piece is not — the nearest precedent it knows is Hindemith, 1942. A striking demo of both music-history knowledge and structural execution.
