The Cb major scale contains the following notes (7 flats):
Cb – Db – Eb – Fb – Gb – Ab – Bb
Cb major is enharmonically the same as B major. It is a very rarely used key and almost not worth paying attention to. It has been included because it has relevance to certain modes and can be a useful reference point. For example, Db Dorian is technically a mode of Cb Major.
I would suggest focusing on B major for now, if you are still trying to get your head around major scales. Otherwise, if you want to get right into it, have a lot at the positions below.
