Source & interpretation
David Temperley’s harmonic analysis of Back in Black ↗, from the de Clercq–Temperley RS 200 corpus. Retrieved 19 October 2026.
The complete field includes all harmonies in the source’s S rule. The passages are its named top-level units; direct chords outside those units still contribute to the whole field. Repeated units with the same notes are merged. Labels such as “Passage A” preserve the source where a conventional section name is not given.
Notes and circle assignments are calculated by Chordfields from that analysis. They have not been independently verified against the recording. Read the full method.
