Harmony analysis

Billie Eilish – Therefore I Am: key and chord analysis

The song opens on Dm and ends on A. Its chords belong to both F major and Dm, so every chord below is read both ways.

Major view

F major

Brightness rank 2/7 (bright)

Characteristic notes

7 = E (leading tone, pulls home)
4 = Bb (the note that leans on the 3rd)

Minor view

D minor

Brightness rank 5/7 (leaning dark)

Characteristic notes

b6 = Bb (the minor's melancholy)
b7 = C (natural-minor colour)
#7 = C# (harmonic-minor leading tone from the V chord)

Which side does the ear lean to?

Our reading: to us the song feels closer to the D minor side because it opens on Dm, Dm is heard 15 times while F never appears and the major V chord points straight at Dm. That is an interpretation, not a rule — the same chords are just as valid seen from F major, and switching between the two views is exactly where the practice value lies.

Chord degrees: major and relative minor

Show the degrees above the chords — relative to F or to Dm; comparing both readings is a practice of its own.

Every chord of the key, listed 1 to 7 separately for each key. Chords played in the song show how often they appear; chords from outside the scale sit next to their own degree.

Analysis

The key pair is F major and its relative D minor (1 flat). 2 different chords appear 32 times in total; 1 of them sit naturally inside the shared scale. The major V of Dm brings the harmonic-minor leading tone, giving the minor side a sharper, more dramatic pull; seen from F, the same A is V/vi, a secondary dominant heading for Dm.

Chord movement

A Dm FV/vi → vi DmV → iharmonic-minor cadence ×14

The move to watch is A → Dm, heard 14 times. From the Dm side it is V → i (harmonic-minor cadence: the major V resolves dramatically); from the F side it reads V/vi → vi. Knowing where these arrivals fall helps you feel the phrasing and anticipate the next chord.

Improvisation tips

F major pentatonic and D minor pentatonic are the same five notes (F – G – A – C – D): start from F for a brighter phrase, from D for a bluesier one.
Over A, land on A, C#, E — the chord's own tones always sound right on strong beats.
Over Dm, land on D, F, A — the chord's own tones always sound right on strong beats.
When A comes, swap the scale's C for C#: that single note is the harmonic-minor sound of the chord.

The song's harmonic story

Starting on Dm, the song gives away its key from the very first bar. A, Dm carry the song: V/vi–vi relative to F, V–i relative to Dm. A is the interesting twist: in F it is a chromatic chord (V/vi), while in Dm it becomes the dominant (V) that makes the minor side sound so determined. Keep an ear on A → Dm (V/vi → vi in F, V → i in Dm): harmonic-minor cadence — the major V resolves dramatically. Ending on A, the song seals F as home.

This analysis is generated from the song's chords by akorculuk's harmony engine using consistent rules. When you change key, the degrees stay the same; only the chord names change.
