concentrate to drums more and it goes away.
Yes. overplaying is thinking about only our part. Listening to the rest of the ensemble -
to the music - is the path away from that narrow focus. Find cool ideas the other players are executing and create space for it.
If it's typical 4/4 back beat music,
a good starting place is to "leave space for the snare"
stop your notes ringing the instant before the snare hits
deliberately play the rests
form the pocket around the snare hits
beyond that, try concentrating on all the other
elements of groove beyond pitch and rhythm.
Articulation, dynamics, note length etc...
When I need to create a bass line, my go-to approach is to find the
minimum appropriate rhythm I can get away with and master that, so I can reach a point of being able to
listen . Then I listen to the ensemble and assess how the whole song feels, and eventually opportunities for more interesting bass ideas become obvious - as well as opportunities to frame others' ideas.
TLDR: listen
