Yes I tried and failed haha, my biggest difficulty being not knowing how to keep track of the chords but the first commetn here actually started solving it becouse, as starting to learn piano too i started looking for new ways to look at things so I tried it.
As simple as it seems , play 1 chord (C7 lets say as i mostly play blues rock) then one measure of most basic blues scale melody then back to the chord and so on, Then doing this with a C7 and F7 ( still just C blues scale) I started naturally playing the chord in my mind which I never managed to do before.
So right now im on the best track I ever been on to start learning to improv. I played over a 12 bar blues for the first time knowing exactly where I am in the structure, and im gonna keep playing having this concept as the base. Like playing “two hands” on the piano. For some this thing might have come very naturally without giving it a name or “strategy” but for me this literally started workin.
So thank you @Riffdiculous !!
Now its just a matter of making vocabulary in context. Thing was I want to be able to play as I had a backing track going without having it if I want to and I had no idea how to do that cuz whatever way of counting I tried my mind couldnt process it. But also I wanted to start using vocal singing ( im not a singer but you know the basic play what you hear) but in context and also mixing it with actual vocabulary from my favorite music. In case anyone wonders what would be a good way to start trying to do that: I recently saw a Josh Smith interview( music is win) : you basically just learrn to sing with your voice and memorize it that way a certain lick, you can’t go " lick hendrix number 15 " , you have to be your literal voice, thats why the greats say music is a languange , you literally speak it, Never understood how to do anything like that until yesterday haha.
If anyone has more ideas or wanna share their way of improvising/composing /using their voice and vocabulary please tell us!!
