I am still a work in progress on this very front my damn self.
but when I get the itch to start back again and again here is my formula.
Get a metronome! my pedals have them and a tuner built into them
and real quick FWIW, the Library is a HUGE resource in my area. lots of stuff for free!
I would start with the nursery rhyme type of songs. Happy Birthday, Twinkle Twinkle type stuff..you should 'know' them so it will be easier to digest from the jump..
First I bought some bass books.
Complete Jazz Bass Book (Mel Bay)
https://www.amazon.com/Complete-Jaz...eywords=Jazz+bass+book&qid=1582649914&sr=8-30
and
Electric Bass Method
https://www.amazon.com/Electric-Bas...9778&sprefix=bass+guitar+boo,aps,169&sr=8-126 (this is the first book I ever bought way back in like 1994

)
and more recently Ed (Bad Mutha) Fuqua's Walking bassics
https://www.amazon.com/Walking-Bass...d+Fuqua+walking+bassics&qid=1582650060&sr=8-1
and I also have an app called 'Music Tutor' (apple store, has a big G clef icon) that is free. you can set Alto, G or F clef (or both/all). you can set accidentals, and a range of notes from A1 to A4 for bass anyhow (if you get the app this bit it will be more explanatory) you can set a timer for 1,5,10 min or infinite.. great app! in a nut shell its like flash cards for music notes. it also will chime the tone for the note which is helpful after a while because you start to get aurally trained too. I use the Music tutor app in line at the store/fast food joint, on a commute (passenger type).
Now for the work.
I suggest EVERY DAY 15-30 mins hit the shed (BEST CASE SCENARIO). If you cant do every day then try for 5, or at least 3 days a week.. IME it is better than just 1 or 2 days. the Mel Bay books take a positional approach which I like.
*NOTE*
Once your 'cup is full', take a break so your brain can process what it is trying to 'digest' and empty out for another refill later on. you know that saying about Rome right???
Work away from your bass when and as often as you can, and with it once you get more familiar with the dots. The books and the app are good for this. as is knowing your bass's notes! (cant stress this enough, know your bass fretboard)
take it slow. *what is the rush?*
oh and finally (at least for this post) buy/download a manuscript book with blank staff lines on it. you can copy some things and eventually create your own ideas. I suggest starting with the Major scale in every key, then the Minors (think circle of fifths/fourths) these two scales are pretty much bread and butter for western music.
Eventually you get enough base to start transcribing lines if you are serious about pursuing reading regularly.. its a step in the process.
I am sure this is far to much for one post, but you get the gist hopefully.
The main things are 1) to start. and 2) to do it daily until you have a good foundation. and 3) repeat to keep you axe sharp.
again work with a metronome/drum machine and start slow.
Good Luck soldier!
