Harmonic Analysis & Structure

Overview

Key: E♭ major · Chords used: 12 · Sections: 5

Form: A Section → A Section → B Section → A Section → B Section

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. This page shows that chart 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 iReal Pro forum charts archived in ChoCo (de Berardinis et al., 2023). Community chord chart “If I Only Had A Brain” (credited “Arlen Harold”, style Medium Swing) 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 D.S./D.C./coda jumps have been written out in playing order.
  • About the song: Wikipedia.
  • Not verified: other charts of this song differ in places from this one, so this page isn't marked verified.
  • Rhythm and chord durations aren't shown; each step is one chord change.
