Relative Minor Scales
Each major key has a relative minor key. The sixth note of each major scale is the root note of the relative minor scale.
For example, the notes of C major scale are:
C D E F G A B C
The sixth note of C major scale is A. A is the root note of A minor scale. A minor is the relative minor of the C major, and C major is the relative major of the A minor scale. The A minor scale (A B C D E F G A ) uses the same notes as the C major scale. The C major scale and A minor scale have the same relative keys, and they both have the same key signature.
