Chords in the Key of F# Major

Diatonic triads

Seventh chords

Stack one more scale tone on each triad and you get the seventh chords — same key, more color.

Common progressions in F# major

• I–V–vi–IV

  F# – C# – D#m – B

  The four-chord pop loop — a huge share of modern radio runs on it.

• I–IV–V

  F# – B – C#

  The three-chord workhorse behind blues, folk, and early rock and roll.

• ii–V–I

  G#m – C# – F#

  The jazz cadence — the strongest pull back home in the key.

• I–vi–IV–V

  F# – D#m – B – C#

  The '50s doo-wop turnaround, still everywhere in ballads.

How the key of F# major works

F# Major carries six sharps (F#, C#, G#, D#, A# and E#). The scale runs F#–G#–A#–B–C#–D#–E#, and stacking every other note of that scale builds the seven chords above — every chord tone comes from those same seven notes. The E# is not a typo: each letter appears exactly once per scale, so the note you might casually call F is spelled E# here.

D# Minor is the relative minor: identical key signature, identical seven chords. A song that treats D#m — the vi chord here — as home base is in D# minor, even though its chord inventory matches this page exactly.

The parallel minor, F# Minor, keeps the same root but flattens the third, sixth, and seventh — its signature shifts to three sharps (F#, C# and G#). Borrowing chords across that line is where a lot of songwriting color comes from.

Playing F# major on guitar

None of the chords in F# major is a standard open chord: F#, G#m, A#m, B, C# and D#m all need barre shapes, which is why most guitarists reach for a capo in this key. The diminished E#dim is usually played as a small three-string shape rather than a full chord.

A capo is the shortcut. With one, the I–V–vi–IV progression (F# – C# – D#m – B) sounds in F# major while you finger open shapes:

• Capo 4 · play it as D major

  D – A – Bm – G

  3 of 4 shapes are open chords.

• Capo 6 · play it as C major

  C – G – Am – F

  3 of 4 shapes are open chords.

• Capo 9 · play it as A major

  A – E – F#m – D

  3 of 4 shapes are open chords.

Work out a capo for any song's chords

Where F# major sits on the neck

The root, F#, is fret 2 on the low E string and fret 9 on the A string, the two places most major barre shapes and scale positions in F# major are built from.

Only the open B string is in the key. Watch the open low E (fret 1 gives E#), the open A (fret 1 gives A#), the open D (fret 1 gives D#), the open G (fret 1 gives G#) and the open high E (fret 1 gives E#).

One note separates F# major from each neighbour on the circle of fifths. Raise B to B# and you are in Db major (usually written with the enharmonic spelling); lower E# to E and you are in B major. Those are the two keys a song in F# major most often modulates to.

Keep practicing

• Practice the F# major scale on the fretboard
• Jam these progressions over a backing track
• Transpose a song into or out of F# major
