Sorry this may seem a little abstract of a question, especially to those of us who are not -yet- pros. I find that you could say (lets not get too tangled up in objections to this theory) that there are two major ways to go about playing the bass, The first is thinking about your playing as a movement of fingers The second is thinking about your playing as a musical sentence, i.e. a measure on a staff While I always find that it is a lot more rewarding to think the second way, because it tends to lead to more creative improvisation, it limits how fast you can play, particularly in slap, because you have to think ahead some about the movement of your hand. I find that playing music as a collection of rhythmical pitches often leads to cooler chunks of melody, however, I find that thinking in terms of notes often has me pausing halfway through a measure because I havent sent instructions down to my fingers quick enough. However, the flip side of this is I often find myself frustrated because I just played two measures of slap doing little more than slapping the octaves during a jam. Maybe Im wondering how those of you who can improv at lots of tempos naturally find some type of harmony (pun intended) between these two types of thought.
