may be the G major scale its only a small part of it. "
you only have 3 lines, am i to assume that the strings are
D
A
E
in which case it would be wrong...or am i to guess that you happened to choose
E
B
G
which would be right?
also, have you ever tried to play like the A Major Scale over an F major song, and just impliment the F note into A Major? a scale is really just an idea, a general idea, since there are no rules in music.
