Good stuff.
The bass is where I get the majority of my pitch sense from when I'm singing, improvising or learning a new song. With singing, I can feel the beating between the notes when I'm off, internally.
I was thinking the other day when comparing what I learned by ear to some tabs, I'd like to make a vid on how I figure out what position/string something is being played on. I was learning Mastodon tune when when I checked the tabs I saw they wrote a part out using the B and E strings, when the part is actually played higher up the neck on the A, D and G strings. The version they came up with was almost impossible to finger
Sometimes just figuring out the position/area I need to be in helps me figure out the rest much easier.
