The Major Scale…But Starting on G

We have taken apart our scale pattern with the C major scale. We started on C and we did two whole steps and a half step, then three whole steps and a half step. What happens if we do a different note? Let’s see what happens if we start on a G. Well, a whole step is a G to an A.

So far we are good. Another whole step is an A to a B. Still good. A half step would be B to C. We are looking good. Another whole step C to D. Good. D to E is another whole step. Still looking good. Let’s take E to F.

Oops. F is actually a half step away from E and we need a whole step. So what we are going to do? We want to make that F sharp. By sharping the F we now have a whole step between E and F# and that gives a half step back to G.


Back when we were first learning the C major scale, we mentioned doing a whole step, a whole step, a half step, and 3 more whole steps, and a half step. Let’s take a look at this as they are – intervals. An interval is nothing more than the distance between 2 notes musically speaking. The first interval is C to D.

C is where we start – so C is one. Technically we could play two of the same Cs together on the guitar, C to C is called a “Unison.” But if we go up to D, the D is the second note in the scale, so we are going to call that D a second.

C to E is a third, F is the fourth, G is the fifth, A is the sixth and B is the seventh.

Any unison, fourth or fifth that occurs naturally within the scale is referred to as a “perfect interval.”

Any second, third, sixth or seventh occurring naturally within the scale is referred to as a “major interval.”
