Simply put, it’s too complex for practical use, and there’s an easier way to express it: with the key of A♭ major (its enharmonic equivalent). Key signatures contain a maximum of seven singular sharps or flats, which we see in the keys C-sharp major and C-flat major, respectively. But, if we were to continue the pattern of sharps, the next key signature would be G-sharp major, which contains an Fx (double-sharp). Additionally, some of the chords native to G-sharp major would be a bit absurd. Take a look: ▪ G# maj: G# - B# - D# ▪ A# min: A# - C# - E# ▪ B#min: B# - D# - Fx ▪ C# maj: C# - E# - G# ▪ D# maj: D# - Fx - A# ▪ E# min: E# - G# - B# ▪ Fx dim: Fx - A# - C# G-Sharp Major’s Alter-Ego For the sake of efficient notation, we can express the same exact scale with only four accidentals by using the key of A-flat major. This key is tonally identical, or "enharmonically equivalent," to G sharp. A-flat major's scale is as follows: Ab - Bb - C - Db - Eb - F - G** **The G in this scale is equal to the Fx.

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