Learning all the keys in one go is a big ask so how about we learn one at a time. Today’s key is F major. F major has 1 flat note. All keys consists of 7 notes (alphabetic letters). So every key will have an A, B, C, D, E, F & G.

In the case of F major one note is a flat note. Bb. So the key of F major is as follows; F G A Bb C D E.
