Stretto
Draw a melodic subject — the machine answers it with a real canon: delayed, transposed, inverted voices that chase your line and self-adjust to stay consonant, crystallizing into a scrolling score.
canon at the 5th · delay 2 beats · 1 answering voice
subject (dux) answer (comes)
Draw your subject — tap a cell in each column to set its pitch (tap again to clear). Time runs left → right; higher rows are higher notes.

Tonic D4 · a small ring above a notehead marks where the consonance engine nudged an answer to stay sweet.
