Relative keys have the same

Answer 1

Relative keys share the same key signature but differ in their tonal center. In music, the relative minor key of a major key is the minor key that starts on the sixth degree of the major scale. For example, the relative minor of C major (which has no sharps or flats) is A minor, which also has no sharps or flats. Conversely, the relative major of A minor is C major. This relationship allows composers and musicians to explore different moods and tonal colors while keeping the same set of pitches.
