Great question. I guess that depends! Some aspects are sometimes instant, and other aspects continue to change for a long time.
The downward pickslanting stuff was nearly instant, in the sense that I could immediately play one phrase, played one way, with whatever picking movement I was using at the time, which I don’t even remember. I was probably already using the technique and just didn’t know it. Some of the other insights, like two way pickslanting, were more complicated because that technique was “figured out” more deliberately, over time, by watching video, experimenting, watching more video, and so on. So the process of learning the technique was intermingled with the process of discovery that the technique even existed. It probably took a year just figuring out that this was even going to work at all.
So I would try not to read too much into how long it took me, since the process was indeed probably much longer than we would like it to be for players approaching it with actual teaching. We’ve already seen stuff on the forum, right here, from new-ish players that is light years quicker than whatever I did. This is the kind of head start we are hoping to deliver, and we can still do a much better job in outlining the different hand movements and setups so it’s less confusion.
@Hanky_Pooh you should absolutely not get discouraged. Nobody does all these movements, not even me. What matters is that you find what you’re good at and do more of it. You’ve proven to be very good at adapting these little licks and exercises into fun musical examples that sound good while being instructive. That’s where your years of music experience come into play. You have a massive head start in musical vocabulary land compared to a newbie. I would immediately start writing licks and lines of your own that use whatever one of these techniques you are currently best at. Once you start to unleash your own creativity with these techniques, and you can play lines simply for their enjoyment, you’ll start to care a lot less about the technical rat race and a lot more about music.
