For this lesson I did a combination of memorization and reading the tab in real-time. For some of the up-the-neck backup I memorized the tab.
But for the other parts I just read the tab as I played it.
I did write the arrangement though so it might be easier for me to read it as I play!
You’re certainly welcome to memorize any parts of the tab you need to.
Otherwise, as the speed increases, you may have to look further ahead in the tab to read it in real-time. This takes practice too.
