Music theory is 'science' ; applying it well is art
Thank you for your answer.
I agree with your statement. Articulation, mood, character, etc... is ART.
But it is the answer to a generically nebulous question
"how do I play changes in a way that isn't boring?"
I can repeat/reiterate over and over again - the bass player's job (or any other musician's) is to make sure that even the simplest note, pattern, riff, groove, etc... is properly articulated in each and every bar/measure

, and fits with the rest of the rhythm section, band, orchestra, maybe, even "serves the song (who knows?).
Most of us - the amateur bass players - tend to forget about it quite often


.
About the "boring" part.
It's like driving to work everyday and taking the same route - samo samo. It could be boring, but it does not mean that the driver should do something else, like texting

, reading a book, or STREET-RACING



, etc... - instead of doing that "boring" driver's thing.
Some other "boring" things like eating

, using a bathroom, dressing

, etc...
In addition to that "boring" part.
I've haven't seen even ONE (1) question from an amateur/beginner bass player here at TB asking what the difference is between two
EXTRA boring and
EXTRA simple bass patterns that Aurally and Harmonically sound so DIFFERENT to me.
That questions has been bugging me for DECADES.
Pattern 1
Pattern 2
What's more. I've heard quite a few songs (popular songs) with those simple bass patterns (including some variations) but USUALLY, a PRO BASS PLAYER has never mixed/crammed those two (DIFFERENT to me) patterns in one song sporadically/intermittently.
Oh, YES. I've heard more than NUMEROUS amateur bass players frivolously MIXING both (DIFFERENT to me) patterns in one song.
P.S. I think I'm just a boring person living in the "Boredom" municipality.
