Couldn't get the video to play - Thunderstorms have made everything wet, and ATT plus water equals slow Internet.

However, I feel guitarists should learn regular notation. Tab could be an addition, but normal notation should be primary.

Why?

Notation is universal. You can play everything, even if you don't know it. Tab books are limited.

I know a guitarist who gets a lot of session work because he can read regular music (I've played sax on more than a few sessions with him).

You can even play with people who don't speak your language.

I admit, reading music on the sax and piano is easier than reading music on the guitar. But every instrument has its gifts and challenges. Transposing is way easier on the guitar. Sax and piano require entirely different fingerings.

So just as the sax and piano person becomes a better player by learning to transpose, the guitarist becomes a better player by learning to read universal notation.

That's my personal opinion anyway YMMV
