Common progressions in F# major

On guitar

Capo 4. With a capo on fret 4, play the open shapes D for F#, G for B, A for C#: they sound as the I, IV and V (F#, B and C#). The vi chord, D#m, does not become an open shape at that fret.

How the chords of F# major work

F# major uses the notes F# G# A# B C# D# E#, six sharps: F# C# G# D# A# E#. Stack every other note of that scale on each degree and you get the seven chords above: three major (F#, B and C#: I, IV and V), three minor (G#m, A#m and D#m: ii, iii and vi) and one diminished (E#dim, vii°). Most songs in F# lean on F#, B and C#, with D#m as the fourth chord.

The V7, C#7 (C# E# G# B), is the chord that sounds like it wants to come home: its E# rises a semitone to F# and its B falls a semitone to A#. A song that ends C#7 to F# is almost certainly in F# major.

D#m is also the home chord of D# minor, the relative minor: it uses exactly the same seven notes and the same seven chords (its page is Eb minor, the same notes written with flats). So a chord list from this page can be in either key; it is usually in the one whose home chord it starts or ends on.

What this page cannot do

  • Only major and minor keys. Dorian, Mixolydian and the other modes are not covered: a song in D Mixolydian (D, C, G) uses the chords of G major and will look like G major here.
  • Finding a key from chord names is a best fit, not a certainty. A chord list cannot tell a key from its relative minor, which shares every chord; the melody and where the song comes to rest decide it.
  • Songs change key. A bridge or a last chorus a step higher is a new key, with its own page.
  • The sound is a simple synthesised tone made in your browser, each chord in root position, not a recorded piano or guitar.
