but a different
tonic. (This is as opposed to
''parallel'' minor or major, which shares the same tonic.)
For example, F major and D minor both have one flat in their key signature at B♭; therefore, D minor is the relative minor of F major, and conversely F major is the relative major of D minor. The tonic of the relative minor is the
sixth scale degree of the major scale, while the tonic of the relative major is the
third

degree of the minor scale.
The minor key starts three semitones below its relative major; for example, A minor is three semitones below its relative, C major.
The relative relationship may be visualized through the circle of fifths.
Relative keys are a type of
closely related key
In music, a closely related key (or close key) is one sharing many common tones with an original key, as opposed to a distantly related key (or distant key). In music harmony, there are six of them: five share all, or all except one, pitches wi ...
s, the keys between which most
modulations occur, because they differ by no more than one accidental. Relative keys are the most closely related, as they share exactly the same notes.
The major key and the minor key also share the same set of chords. In every major key, the triad built on the first degree (note) of the scale is major, the second and third are minor, the fourth and fifth are major, the sixth minor and the seventh is diminished. In the relative minor, the same triads pertain. Because of this, it can occasionally be difficult to determine whether a particular piece of music is in a major key or its relative minor.
Distinguishing on the basis of melody
To distinguish a minor key from its relative major, one can look to the first note/chord of the melody, which usually is the
tonic or the
dominant (fifth note); The last note/chord also tends to be the tonic. A "raised 7th" is also a strong indication of a minor scale (instead of a major scale): For example, C major and A minor both have no sharps or flats in their key signatures, but if the note G (the seventh note in A minor raised by a
