An "a-ha" moment!

Yay! My work on diagonals is paying off. I saw a grand diagonal of E4s all the way across the fretboard from string 1 to string 6. That was exciting because it was a moment of complete peripheral vision: in other words, I can see where a particular scale is in every place it happens all over the fretboard in one glance. That has never happened before . . .
