Minor key signatures

Minor key signatures

Of course, minor keys can use key signatures, too. In fact, for each major key signature, there is a corresponding minor key that shares its signature. Major and minor keys that share the same key signature are called relative keys. For example, both C major and A minor have zero sharps or flats. A minor is considered the relative minor of C major; likewise, C major is considered the relative major of A minor. Compare the minor key circle of fifths below with the major key circle of fifths above, and you'll see the remaining relative key pairs.
