Analyze a Progression — Roman numerals & key: the opening bars as grafer engraved them — The notation, exactly as grafer engraved it from the graph.

How it is built

Analyze a Progression — a familiar tune harmonized, then read back as Roman numerals + tonal function by the Analyze Harmony node, with the key inferred automatically (Krumhansl-Schmuckler). The same progression is voiced SATB so you can hear what is being analyzed. Feed a Reharmonize node into Analyze to see it name the chromatic chords.
