No capo needed. The i, iv and V (Am, Dm and E) are all open-position chords already.

How the chords of A minor work

A minor uses the notes A B C D E F G, no sharps or flats: the natural minor scale, the same notes as C major, its relative major. Its chords from the scale are i Am, ii° Bdim, III C, iv Dm, v Em, VI F, VII G.

In practice most songs in A minor play E or E7 as the V chord instead of Em: raising G to G# gives a note a semitone below A that pulls back to it. That raised seventh comes from the harmonic minor scale (A B C D E F G#). So a song with both G and E in it is still in A minor, and the finder counts E and E7 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.
