Major scale consists of whole and half steps. This example is in C major.
When a major scale starts from another pitch the same structure is achieved by accidentals (sharps and flats)
G major
D major
F major
Bb major
Key signature
The key signature is placed after the clef indication at the beginning of a staff.
Key signatures from left to right: C major, G major, D major, F major and Bb major. Accidentals in a key signature always apply to any octave.
-
Relative keys are the major and minor scales that have the same key signatures. A pair of major and minor scales sharing the same key signature are said to be in a relative relationship. The minor key starts third below its relative major.
A minor is third below its relative, C major.
Other relative keys:
- G major and E minor (one sharp, 1 #)
- D major and B minor (2 #)
- F major and D minor (1 b)
- Bb major and G minor (2 b)
Compare major and minor scales starting on the same pitch:
- D major (D E F# G A B C# D)
- D minor (D E F G A Bb C D)
The most noticeable difference is the 3rd note (major third vs. minor third).
