Form: A Section → B Section → C Section → D Section
Where these chords come from: a lead sheet of this public-domain song, contributed by a musician to the Wikifonia archive and preserved in the OpenEWLD lead-sheet collection (Simonetta et al., 2018). It describes the song as written, not any particular recording. This page shows that lead sheet 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.

Sources & accuracy
- Chords: the OpenEWLD lead-sheet collection (Simonetta et al., 2018). Community-contributed lead sheet (chord symbols over the melody) from the Wikifonia archive, MIT licence. Title and songwriter credit as written on the sheet.
- Section names: detected by code from repeated 8-, 12- and 16-bar phrases (letters such as A and B mark different phrases; a phrase that comes back keeps its letter). Lead sheets rarely print section names.
- Not verified: only one lead sheet of this song is available, so it hasn't been cross-checked.
- Rhythm and chord durations aren't shown; each step is one chord change.
