Any chance you can start to notice when/where the “Bam!” happens? Going for certain notes? Certain strings? Certain fingers? Certain changes between string and fingers?
Maybe a few more details would lead to more detailed pointers… but in the meantime - I’ll add this longer post for those who care to read a neat way to conceptualize developing any new technique - in anything*
As any technique develops, it moves through the 4 stages of learning:
1.) Unconscious incompetence
2.) Conscious incompetence (now you can actually start to address the problem!)
3.) Conscious competence (the long period of working & practicing)
4.) Unconscious competence (the part where your attention and focus can finally move on without backsliding / losing the progress you’ve made)
So as any technique is in this spectrum, just remember that it will take a long time before you’re able to do it without thinking about it. BUT! You will get there… and once you do, you’ll be able to focus much more closely on whatever new thing needs work.
The idea that your body is doing strange things without your permission is firmly in stage 2. “AWARENESS CURES!” as my college bass professor would allllllways say.
So as your familiarity with the instrument develops, as your right hand becomes more comfortable, as the material becomes more comfortable, there will be more and more focus for you to apply to the technique problem in the Left Hand.
Then - you’re at stage 3 - willing and watching yourself to make sure you’re correcting the technique and working it out correctly each time.
Then… over time - it moves into step 4, and you’re shredding with your LH.
And all of this after I deleted 2 other sections…
