well i wont say that im too old to learn new tricks, but sheet music seems a bit out of my grasp right now. i have been focusing on theory a lot more in the last year, and feel like i am finally taking music a little seriously after 20 plus years. im not sure i would agree that you cant play at all tho! for sure in certain contexts without perfect timing it wont work. im thinking chamber orchestra. but when i play with other people, yes, i may bump a bit here or there but i feel like i dont notice it, or that its just part of the live playing experience. for sure soloing at home with o ly a bass is another one of those times that playing with a metronome seems imperative. and yeah, i do feel like i cant play at all a lot lately
then at least you can put the metronome at maybe 60 bpm. This pulse will be you quarter note. So the note should land directly on the clic each time.
then you can try 8th note... so 2 notes for each clic ... one that land on the clic and one that will be in the space between.
as you guessed it 16th note are for 4 notes for each clic, one note will land on the clic and 3 will be in the space between.
of course all of that you need to play each note evenly, letting each last the same amount of time... like with the 16th note don’t land the first one on the clic and letting it last longer and then rush 3 notes before the next clic.
this is why reading music and so having a teacher for that part help a lot. You will be a lot more solid as a player with playing with other. You will be able to read music and on a recording it is impossible to hide your mistakes so ... this is where you really show how solid and how you can really play.
