The relative minor of a major key has the same key signature and starts down a minor third (or equivalently up a major sixth); for example, the relative minor of G major is E minor. Similarly the relative major of a minor key starts up a minor third (or down a major sixth); for example, the relative major of F minor is A♭ major.
Keys are expressed in readable strings, e.g. C major or Ab minor
