Hi I am currently using the second round. I have been trying to develop a wrist motion picking motion, working on a nice movement at 170-180bpm, then slowing it down. I have found that working on round 2 is of some help, or at least I have made progress through it over a period of time, which makes me think that I am progressing somewhat. I take it it is at about 120 bpm? I don’t think round 1 is worth it: too slow to be sure you are using an efficient picking motion. Once round two moves into the two note per string pentatonic type shapes, I find I am falling apart with it.
I also use the 3nps scale bit; I find it tricky (again I am taking it to be around 120 bpm) but probably useful to work on.
I have found great benefit with Guitar Playalongs on YouTube for my left hand, this has really made a big difference for me. I have found more benefit to these, than practising left hand kind of material on my own, for whatever reason; I maybe just wasn’t as consistent or doing it for long enough before??
Plus, I like practising along to these kind of interactive videos like that. It’s how I would have done it all along, had YouTube been available when I was 16 or 17!!
