Formula:
The key signature is derived from the **Circle of Fifths**, which systematically organizes all 12 major and minor keys. Each step around the circle adds or removes a sharp or flat.
For major keys, the order of sharps is **F-C-G-D-A-E-B**, and the order of flats is **B-E-A-D-G-C-F**. Minor keys share the same key signatures as their relative major keys, found three semitones (a minor third) below the major key.
