We are kind of derailing this thread, but the mods can move it if they like.
I've been posting and reposting this reply, so I'm not sure which ones you've seen. I'm trying to be helpful, just not sure how to say I think you're making it way too hard on yourself. We don't learn all the words in the dictionary before we can speak and communicate effectively. To the contrary, we only learn a couple of words before we start doing that.
You are way ahead of me in detailed knowledge and there really isn't a 12-bar blues song I won't play or fake.
Seriously, if you feel after all this time with all this knowledge, you can't play music at all, stop and back up.
Master just 3 movable chords and one simple solo in one box pattern and put those chords and solo to work for you in every key and at different tempos and rhythms using 12-bar blues backing tracks.
If it were me, I would refuse to play anything else until you can do this. It's
a very limited amount of actual material to master. Play it over and over in as many situations as you can come up with and see the commonality in all these songs.Â
Record yourself with the backing tracks until the songs sound good. Don't try to completely mimic what you hear on the tracks, just try to fit in with the other players. Your job is not to play on top of them. After all, they are already taking up that space.
From one tune to another, "all" that changes is your timing and rhythm. Otherwise, play the same chords and notes. I don't mean to imply that's easy, but it doesn't involve memorization or reading music. It involves doing lots of reps of the same thing.
Tap your foot, use your ears and listen carefully to each track and try to blend in with the other players. Listen for and anticipate the chord changes by counting or catching signals from the drummer, depending on how good you feel about counting at this stage. Regardless, change chords when the band changes chords. The chord progression is always the same. Your solo notes will always be the same.
One solo and three movable chords is not a lot of muscle memory or memorization and you will truly be able to make music enough to get up and jam with a band.
Why do you think everyone recognizes a B.B. King lick, or a Clapton lick or a Stevie Ray lick? Because they played basically the same thing over and over
in their own ways. You can too.
