Re: An intermediate exercise I came up with
I like to do every possible variation
Do them from low to high strings, from high to low strings, skipping strings, up and down the neck, etc.
It's one complete "set" when you go from low to high (E string, A string, D string, G string, B string, E string) and back. Mess up anywhere on a set and start the set over slower!!
So you do 1234 on the low E and then 1234 on the A string and then 1234 on the D string and so on up to the high E, then you go back down to the low E. That's one set.
Some of them will be easy. Some will be hard, and you'll be like "wtf why do I keep messing up?!" lol.
