find relative minor key from major key
To determine the relative minor of a major key, you can move three steps to the right in the circle of fifths to locate its relative major. For instance, beginning with C major, we progress to C → G → D → A, indicating that its relative minor is A minor. Likewise, to find the relative major from a minor key, you can move three steps to the left.
