Chords in the Key of F# Major

What are the chords in F# major?

Take the F# major scale — F# G# A# B C# D# E# — and build a chord on each note by stacking every other scale note on top of it. Those seven chords are the chords in the key:

• F# — I, major, built on F#
• G#m — ii, minor, built on G#
• A#m — iii, minor, built on A#
• B — IV, major, built on B
• C# — V, major, built on C#
• D#m — vi, minor, built on D#
• E#dim — vii°, diminished, built on E#

The pattern of qualities is the same in every major key — only the letters change. Learn the numerals and you can find the chords of any key in seconds.

Which chords to play first

F#, B and C# — the I, IV and V — carry most songs in F# major. Add D#m (the vi, the relative minor) and you have the four chords behind a large share of popular music.

• Pop Anthem — 1–5–6m–4 — F# – C# – D#m – B. Heard in Let It Be (verse), Don't Stop Believin'.
• Rock / Country / Blues Backbone — 1–4–5 — F# – B – C#. Heard in Wild Thing, Twist and Shout.
• 50s / Doo-Wop — 1–6m–4–5 — F# – D#m – B – C#. Heard in Stand By Me, Earth Angel.
• Rhythm Changes Turnaround — 1–6m–2m–5 — F# – D#m – G#m – C#. Heard in I Got Rhythm, Heart and Soul (original).

The same chords as 7ths

Stack one more third on each and you get the seventh chords of F# major: F#maj7, G#m7, A#m7, Bmaj7, C#7, D#m7, E#m7♭5. Same roots, same function, a jazz and soul colour. The V as a dominant seventh (C#7) is the one that pulls hardest back to F#.

F# major and Eb minor share every chord

Eb minor uses the same seven notes as F# major, so it has the same seven chords — the relative minor. What changes is which chord is home: F# in F# major, D#m in Eb minor. A song can drift between the two without changing a single chord shape.

How to practice the chords of F# major

1. Play F# – B – C# – F# slowly, one strum per chord, until the changes are clean.
2. Open the chord builder in this key and turn on Smooth Voice Leading — it re-fingers each change so your hand barely moves.
3. Then play the scale over the chords. Every note of F# major fits every chord above, which is why the scale and the key are the same thing seen from two sides.
