Piano chords, voicings & structure breakdown · 42 steps · 18 unique chords

Community lead sheet. These chords are as written in a lead sheet of this public-domain song, contributed by a musician to the Wikifonia archive. They describe the song as written, not any particular recording, and no second independent lead sheet was available to cross-check against, so this page isn't marked verified. Section names are detected from repeated phrases, not printed on the sheet.

Harmonic Analysis & Structure

Overview

Key: C major · Chords used: 18 · Sections: 4

Form: A Section → B Section → A Section → C 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.
