Most beginners pay attention to how many notes and how fast.
Most Veterans pay attention to which notes, when to pluck them, how long to let em ring, and when not to play them, as well as the above.
If you're experimenting with less is more, don't underestimate the effect of the duration of your notes.
If the drummer is playing typical rock beats with the snare on 2 & 4
try stopping your notes at just the instant before those snare hits.
(A tip I gleaned here on TB) Instant tightness!
anecdote:
an audio engineer for the original Star Wars film was once asked how to make an explosion sound really huge , like the death star explosion.
He replied "make sure that right before the explosion, it's completely silent."
More and more I find myself silencing my bass preceding a big change.
That's kind of a funny story considering that what you hear before that moment is a series of repeated gigantic orchestra hits.
