Well, last monday my bass teacher taught me about artificial harmonics, and due to a series of events involving drama club, choir, work, 2 psychology projects and a chemistry test, I really haven't gotten the hang of them until tonight. I was originally trying to do it with my thumb, but I just couldn't shift because the side of it kept bumping the fretboard! So I experimented with different wrist angles and finger positions, and settled on putting my index finger on the spot and using my pinky to pluck the string -- thus freeing up my thumb and 3 fingers on my left hand for, say, polyphony. I'm all about the polyphony -- it just sounds so cool. I'm practicing contrapuntal tapping as well (now, I'm not very good at it yet, but it's getting better). Now, what would be the best way to go about this? I don't use my thumb very often, but I figured if I practiced using the artifical harmonics until I had a certain degree of skill and practicing with my thumb until I had a similar degree of consistency, power, and speed as using my two fingers, then I could slowly work my way into merging the two. Are there any specific exercises you folks might reccomend? Also, any specific tapping exercises? Thanks for the help.
