Chaingraph Sonification

Enter the node identifiers of a chain in order, and this page turns each one into a note using a frozen scale table and a fixed fingerprint. The same chain always yields the same note sequence, so a composition derived from a provenance graph can be regenerated by anyone holding the graph. Change one node id and you hear a different piece.

Data: Equal temperament A4 = 440 Hz (ISO 16) · no external data

Inputs STEP 1
Any label you want stamped into the composition.
Integer, clamped 0 through 6
One node id per line. Order matters, it becomes the melody.

This derives pitch only. It does not render or play audio, and it does not claim to be a full composition system. It shows that a graph maps deterministically to a note sequence. Try reordering two of the node lines above and re-running: the melody changes even though the same set of nodes is present.
