Where these chords come from: an expert transcription of the original recording made for the Isophonics reference annotations (Centre for Digital Music, Queen Mary University of London). This page shows that transcription as-is: the analysis below is generated directly from it by code, not written by AI. Consecutive repeats of a chord are shown once, and the piano voicings are our playable arrangement of each chord symbol, not a note-for-note transcription.
