I think so, yes, but I’m not sure myself – wish I was a bit better so I could run these experiments on myself, but were I at that stage, that’s exactly what I’d do, with a minor modification. I wrote about this pretty extensively already in another thread, check it out and see how it feels.
I think you’re at a really interesting stage, and to keep pushing the envelope and progress I think you’ll need to keep experimenting, and keep loose. Pushing through it / building endurance isn’t the answer, I don’t think … I feel it’s more about really paying attention, and finding what makes things click, even incrementally. The techniques above (bursts, rhythms, accents, volume variations) are all about working your nervous system to help it find out what works.
What I’ve been doing recently, which feels useful though it’s still early days, is keep a very simple practice journal for any given lick. I work at one lick for say 10-15 mins, trying various techniques/variations, and at the end of that I record what I did, and also the max speed I hit with that lick. I do a cool down too as mentioned in the above thread. I’m not expected to see speed increases every day, sometimes things won’t click, but over a week or so I would expect to see something.
Recently I posted a “breakthrough” post with a video. As you’ll see, I’m not as good as you, but I’ve definitely improved quite a lot over the past couple of months. I’ve only really started the journal idea very recently, but it feels right. I still have some tension etc to work through!
You’re a super player, so some thoughts:
- always bear in mind how far you’ve come.
- a lack of progress isn’t a failure, it’s an indication that your current methods maybe need some adjusting. It’s feedback and new info to incorporate into your search. Take a moment, take a breath, and think about how you can continue your experiments. And keep avoiding tension.
- “don’t make any attempts for a while.” – yeah, keep chipping away at it bit by bit, if you take a break your body will likely not adjust. It’s like going to the gym, but in this case you’re not building muscles, you’re tuning your nerves and reflexes. Too long a break / infrequent tests = nothing adapts.
I have the same questions with my playing as you, so this is advice for me too.
