It's obvious that the right hand is the time keeper, but what part of the right hand technique keeps the time? I've assumed that it is merely the attack of the note at the right spot that is the time. Where the right hand pulls and makes the note come out is where the time is. However, it is a lot more than that. IMO, The process in which your hand pulls down the string and gets ready to pull the next note is where the time actually is. Your hand pulls the note and must dampen the string right before the next note in order to play. The rhythm in which you pull (note rings) and dampen (note stops) is where your time feel and your swing actually resides. I'd like to compare it to the drummer's ride cymbal. For example, drummers can hit on merely the 1 of the beat and leave out the triplet. Here their swing is implied. once they start hitting the first and the 3rd triplet, their swing is evident. This must be the same in the bass. Your finger pulling the string and your hand dampening the string must have a rhythm (which once you get it down sounds very much like the drummer's ride cymbal). Moral of my story? There's a lot more going on than just the note you play. The way your hand acts in between the notes and the length of your note is what really keeps the time and helps the swing. I just had a lesson and was basically told that my time is not as together as it should be, so this post is more for me. this discussion of right hand technique with my teacher and the space and motions in between notes completely opened a can of worms on me. i'm going to leave this open to discussion since i feel that this is a big issue for many of us in the rhythm section. p.s. the pull and the dampen shouldnt be exactly like the ride cymbal. i just used that as an analogy.
