Yeah no, a good bass line is absolutely essential to a good song (or good performance of a song) in my opinion. Not only that, but a good bass line that has a
groove will make people want to dance to it. Take this cool calypso bass line (I’ve been practicing this one for the show). Also practicing palm muting on this, cause it sounds WAY better in this case. It just works so well cause it has a nice groove. I just wrote out the line isolated from the rest of the arrangement to make it less confusing. (Realized I could've beamed the dotted eighth notes, but whatever, it's fine for the sake of an example).
In swing (when playing a walking bass line),
the most important thing is to play the notes legato (connected), or else there's no groove.
Another great bass line is off of Ray Barretto's version of Killer Joe, if you wanna check that out.
