From trumpet to sax to bass I have found this incredibly frustrating.
I totally get where a bass line mostly should/would lock in with the drummer and keep time, however…
This tune is not this, nor is a lot of brass or sax music, and it is okey dokey to do it.
There are a lot of instructors that say you must keep the beat.
Really? Ask Ella, Louis and a zillion others if they ‘keep the beat’.
nope nope nope
You can express yourself musically any way you wish, and if you are not the ‘locked in force’ driving / keeping the beat, stretching time is a natural things for almost any instrument.
Of course this means lengthening or shorting notes around the beats, not beating to a different drummer, but perfectly acceptable, no matter what anyone says.
When I played trumpet I mostly played New Orleans trad jazz stuff. Louis Armstrong’s phrasing was what gave birth to a whole new concept of playing. My classically trained instructor played to stuff so dry it hurt.
You do you, we like it that way.
