The C minor scale is the ? Of the C major scale
relative minor
The C minor scale is known as the relative minor of the C major scale. In music theory, every major scale has a relative minor scale, and vice versa.
To find the relative minor of a major scale, you need to locate the sixth note of the major scale. In the case of C major, the notes are: C, D, E, F, G, A, and B. The sixth note is A.
So, to find the relative minor of C major, you would play the A minor scale. The A minor scale consists of the same notes as the C major scale, but starts and resolves on A instead of C.
Therefore, the C minor scale is the relative minor scale of the C major scale.
