In Western music, the adjectives major and minor can describe a musical composition,movement, section, scale, key, chord, or interval.

Major and minor are frequently referred to in the titles of classical compositions, especially in reference to the key of a piece.

The difference between the major and minor chord may be seen if they are drawn in chromatic circle.

With regard to intervals, the words major and minor just mean large and small, so a major third is a wider interval, and a minor third a relatively narrow one. The intervals of the second, third, sixth, and seventh (and compound intervals based on them) may be major or minor.

The other uses of major and minor, in general, refer to musical structures containing major thirds or minor thirds. A major scale is one whose third degree is a major third above thetonic, while a minor scale has a minor third degree. A major chord or major triad, similarly, contains a major third above theroot, whereas a minor chord or minor triad contains a minor third above the root. In Western music, a minor chord, in comparison, “sounds darker than a major

The major scale or Ionian scale is one of the most commonly used musical scales, especially in Western music. It is one of the diatonic scales. Like many musical scales it is made up of seven notes: the eighth duplicates the first at double itsfrequency so that it is called a higher octave of the same note (from Latin “octavus”, the eighth).

The simplest major scale to write is C major, the only major scale to not require sharps or flats:

C-D-E-F-G-A-B-C ( C major scale )

The major scale had a central importance in European music, particularly in the common practice period and in popular music, owing to the large number of chords that can be formed from it.^{[citation needed]} In Carnatic music, it is known as Dheerasankarabharanam, and in Hindustani classical music it is known as Bilaval.

F♯ major or F-sharp major is a major scale based on F♯, consisting of the pitches F♯, G♯,A♯, B, C♯, D♯, and E♯. Its key signature has six sharps.^[1]

Enharmonic	G♭ major
Component pitches

See also: F major and G-flat major

Its relative minor is D♯ minor (or enharmonically E♭ minor). Its parallel minor isF♯ minor. Its enharmonic equivalent is G♭major. In writing music for transposing instruments in B-flat or E-flat, it is preferable to use a G-flat rather than an F-sharp key signature. If F-sharp major must absolutely be used, one should take care that B-flat wind instruments be notated in A-flat major, rather than G-sharp major (or G instruments used instead, giving a transposed key of B major), and D-flat instruments in F major instead of E-sharp major, in order to avoid double sharps in key signatures.
