Extending The Scale
First let's add our extra notes to the pattern. We could keep going up after our highest note, but instead we're actually going to extend in the other end. So instead of having the 5th fret of the G-string be our lowest note, we'll now add the 4th fret. I'm using my index finger for this one as well.
This is the same note as the 7th fret of the high E-string only a lower octave. And again, if you're confused by this octave concept think of our grown man and the kid singing a melody together. They're singing the same notes, but one is higher than the other. And if it doesn't make any sense, don't even worry about it. It'll click all of a sudden!
Now we'll add two more notes and those will be the 7th and the 5th fret of the D string. Now when we practice this together, we'll start on our lowest note going up towards the high strings. Then when we reach the top note, we'll breathe for a second and then we'll come back down the scale. I'll count us in really slowly, and then we'll play the scale as quarter notes, meaning one note per count.
Now let's try this out together, and then afterwards you should try it on your own at whichever tempo feels comfortable for you whether it's faster or slower than this.
