so my question should realy have been:
what's the difference between a scale of F# which would have been built from the F scale (correct?) and the Gb scale, which would have been built from the G scale..
could it be that for the F#, we are ascending up the keyboard/piano ,& 4 the Gb, we are descending?
Right now, that is my guess/ how I help myself to understand it.
Try understanding it this way man. When you start on a particular note, whether you name it with #'s or b's, you can only use each proceeding letter once. That is how I would start off learning each scale. Example:
F#Go ahead and list all the letters from F to F:
F
G
A
B
C
D
E
FNext, put in your starting and ending notes:
F#
G
A
B
C
D
E
F#Then, use the major scale formula (W W H W W W H) to fill in the rest of the notes. If you do it this way, you don't have a choice in what to call the notes cuz the scale formula will dictate that for you:
F#whole step
G#whole step
A#half-step
Bwhole step
C#whole step
D#whole step
E#half-step
F#I'll do Gb so that you can see that scale as well.
