I am in the process of studying scales and modes and have a question regarding the Gb major scale.
The scale is Gb-Ab-Bb-Cb-Db-Eb-F. Now if I were to follow the W-W-H-W-W-W-H then this doesn't make sense.
Bb-Cb is a whole step but B to C can only be a half step so wouldn't that make the scale Bb-C?
I hope I am making sense here and not causing everyone to go cross eyed. From what I learned E to F and B to C can only be half steps, therefore the Gb scale is wrong in my eyes.
Is there something I am not seeing here or is there an exception to the rule?
Thanks in advance!
