Scale Theory (cont.)
The "G" scale we talked about would be (one sharp in the key signature):

G = 1 or I
A = 2 or ii
B = 3 or iii
C = 4 or IV
D = 5 or V
E = 6 or vi
F# = 7 or vii

The "D" scale would be (two sharps in the key signature):

D = 1 or I
E = 2 or ii
F# = 3 or iii
G = 4 or IV
A = 5 or V
B = 6 or vi
C# = 7 or vii

Let's look at the "A" scale (three sharps in the signature):

A = 1 or I
B = 2 or ii
C# = 3 or iii
D = 4 or IV
E = 5 or V
F# = 6 or vi
G# = 7 or vii

Notice the names of the note proceed alphabetically. Even though C# and Db are the same note "enharmonically", you wouldn't play an Eb in the key of "A" because note number three has to have some kind of a "C" note, not a "D". Follow me?
