You know the ones that either literally or almost literally stay the same throughout most of the song....Do they bore you, playing or listening? Do you think they have their place in a given song/genre? Frankly, if it's not some over-noisy, rehashed synth line in a techno song or something I can appreciate it as much as any other bassline in a number of senses. The ultimate has got to be Papa Was a Rolling Stone. Such effectiveness and cool in just 3 notes. I've heard a version with a regular bassline and it's not nearly as powerful. Others are "Chain of Fools", "If I Needed Someone", and I really like "Body and Soul" (Love & Rockets) where after a mostly steady bassline David J bookends the song with these lovely, heavy runs - and those runs would not be nearly as effective if not for all the buildup. Also I'm wondering is there a musical term for these kinds of figures? Ostinato maybe? I've seen the term Static Harmony, in reference to If I Needed Someone, used exactly once but it seems to make sense.
