Common progressions in F# minor

On guitar

Capo 2. With a capo on fret 2, play the open shapes Em for F#m, Am for Bm, C for D: they sound as the i, iv, V and VI (F#m, Bm, C# and D). C# still has no open shape there; play it as a barre chord.

How the chords of F# minor work

F# minor uses the notes F# G# A B C# D E, three sharps: F# C# G#: the natural minor scale, the same notes as A major, its relative major. Its chords from the scale are i F#m, ii° G#dim, III A, iv Bm, v C#m, VI D, VII E.

In practice most songs in F# minor play C# or C#7 as the V chord instead of C#m: raising E to E# gives a note a semitone below F# that pulls back to it. That raised seventh comes from the harmonic minor scale (F# G# A B C# D E#). So a song with both E and C# in it is still in F# minor, and the finder counts C# and C#7 as belonging to this key.

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 major, 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.
