Hi Rob. Just before you get to the Awesome Major Scale Exerecise there are the 12 major scales written out for you to learn them.
The actual exercise is just that, an exercise I did probably hundreds of time that really helped me to develop technique.
once you do it in a few different keys (scales) you’ll see the pattern and how it works…very simple (moving up one note at a time until the entire scale is played)
if there are only 8 fully written out as you say I’m not sure if I forgot to include the rest or most likely didn’t feel it was necessary because of the repetition.
