Where these chords come from: a chord chart of this song written by a musician and shared on the iReal Pro forums, archived in the iReal Pro forum charts archived in ChoCo (de Berardinis et al., 2023). It's one musician's reading of the song, not a transcription checked against the recording.

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 iReal Pro forum charts archived in ChoCo (de Berardinis et al., 2023). Community chord chart “Alligators 427” (credited “Thiéfaine”, style Rock Pop) from the forum file linked here, CC BY 4.0 via ChoCo. Performer/songwriter confirmed from Wikidata.
  • Section names: from the chart's own markings: section names written on the chart (Intro, Verse, Chorus…) are kept, and rehearsal letters are shown as “A Section”, “B Section” and so on (the B of an AABA song is called the Bridge).
  • Chord charts are often written in a key that suits a particular singer or band, so this may not be the key of the original recording.
  • The chart's key setting didn't fit its chords (it was probably left at a default), so the key shown here was worked out from the chords.
  • Not verified: only one chart 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.

Every chord on this page comes from the community chart listed first below. Piano voicings are our arrangement of the reported chord symbols, not a note-for-note transcription.

  • Chords from a chart a musician wrote and shared on the iReal Pro forums (archived in the ChoCo research dataset); may be in a different key from the recording, and not checked against it.
