Demo
This demo uses examples/melodies/bach_wtc1_c_major_prelude_upper.musicxml, a two-measure monophonic incipit derived from the public-domain BWV 846 entry shipped in the music21 corpus.
Run the same example locally:
uv run canonize generate examples/melodies/bach_wtc1_c_major_prelude_upper.musicxml \
--out tmp/demo \
--engine repair \
--top-k 12
The selected preview is the rank 1 repair candidate from this run: repaired inversion, delay 4, score 86.0. In a listening pass over the retained demo candidates, it was the most pleasant clip even though a stricter transposition candidate scored higher under Kithairon's rule penalties.
Input
Selected Repair Candidate
The score breakdown shows why this relaxed candidate still pays weak-beat dissonance penalties under the current scoring model.
Strict Comparison
The best strict fallback keeps the follower as an exact transposition transform with delay 4.
The second retained strict candidate uses a wider delay.
Web View
Start the visualization API and frontend as described in Visualization, then upload examples/melodies/bach_wtc1_c_major_prelude_upper.musicxml.
