Since the C C natural minor scale had E E, A A, and B B, the key signature of C minor has three flats, written in the order of flats B B, E E, A A. So if C♭ is the second to last flat, so F♭ is the last. Minor key signatures agree with the notes of the natural minor scale. The second to last flat (♭) of the key signature is always the degree I of the scale, and degree I is also the name of the key: You already know perfectly the order of flats: B♭ E♭ A♭ D♭ G♭ C♭ F♭

Major scales with the word flat (♭) have key signatures with flats, so C flat major has one or several flats. With your brain and rules of music theory:

Major keys are in the colored parts of the circle, just find C♭ and read how many flats they are: seven flats! įinding C♭ major key signature with the circle of fifths is very easy, you just had to read the circle: To find the C flat major key signature, there are two methods: The circle of fifths or your brain.
