I did a partial analysis of Solo 1 a couple of years ago for another Bgu'er
That's above and beyond the call of duty. I'm just going to point out one more thing and then I'll give it a rest.
Each explanation starts with a diagram of a box for a particular scale.
What the OP is describing would be like only showing the notes inside each red "loop" without any heading stating what box or scale it is.
Simply memorizing seemingly random notes in order by rote.
Others have suggested breaking them up into smaller groups, which we all agree will make it easier to memorize smaller groups of seemingly random notes linked in a seemingly random order of groups.
We all have to memorize individual phrases and memorize how they are strung together.
All I'm suggesting is that being able to relate each phrase to a scale in a particular pattern in a particular area of the fretboard and then realizing there is a "logic" to how the phrases are related and follow each other will only
make memorization "easier".
Otherwise you just have a lot of random notes strung together without any way to organize them in your head.
I just "re-learned" Changing Modes Solo 2 in Griff's Modes Unleashed course.
First time I learned it I didn't watch the videos. I just put it in my looper/slow downer and memorized it "by rote", phrase by phrase.
It took me at least 10 days.
This time I watched the videos. I took notes in my manual. I noted every time Griff described changing a scale or a pattern and why he did it.
I memorized it in an afternoon.
You might think it went faster because I was already familiar with it. But I'd completely forgotten it.
This time I took the time to learn where every note is in a scale and which box it's in and why Griff was using it when he did.
It was no longer "random".
