The Pattern of Accidentals

Memorizing the order in which the accidentals appear in the key signatures will ease both sight-reading and musical composition, and help strengthen your understanding of the diatonic scale. You'll see this pattern everywhere in music theory, so it's valuable to to know (notice in the examples below that the pattern is simply reversed):

  • Sharps (#): F     C     G     D     A     E     B
  • Flats (b): B     E     A     D     G     C     F

• Understanding the Key Signatures
Everything you need to know about the accidentals & key signatures.

• There are always two keys that relate to one another more than any other key. Find out what this means.

• Comparing Major & Minor
Major and minor are often described in terms of feelings or mood. The ear tends to perceive major and minor as having contrasting personalities; a contrast that is most obvious when the two are played back to back. Learn more about major and minor scales and keys.

• The 6 Enharmonic Key Signatures
If you’re familiar with the circle of fifths (see above) or you just know your way around the key signatures, you may have noticed a few anomalies. Some keys – like B-sharp and F-flat major – are seemingly absent, while others go by two names

• The Inefficient Keys
The circle of fifths shows only the working scales. But, if we expand on its pattern, we can see that it’s actually more of an infinite spiral, so there’s no end to the possibilities of musical scales.
