Key Signature

The sharp and flat have fixed position and sequence in key signatures.

#: Father Charles Goes Down And Ends Battle
b: Battle Ends And Down Goes Charles's Father

Sharp Key Trick - For keys that have sharp, find the last sharp and go one note higher. If the note is sharped in the key signature, the key is sharped.

For example, for A Major, there are 3 sharps. The last one is G. So the key is A Major. For F# major with 6 sharp, the last sharp is on E. since note F is sharped, the key is F# Major.

Flat Key Trick - Find the second last flat (from the right). The name of the flat note is the name of the key. Similarly, if the note is flatted in the key signature, the key is flatted.

For example, Ab Major with 4 flat, the last flat is D and the second last flat is A. As note A is flatted in the key signature, the key is Ab major
