| I used to play it, I would pratctice it on a pbass first, then on my jazz it was easier (not easy though).
I've also learned it on the piano, and the other part of the sheet is not playable on bass guitar.
the "first part" is the only one playable on bass.
learn it very slow first and then build up your tempo.
I used to play it very slowly up to jaco's tempo to warm up my fingers.
but speed is not that important (except if you want to play it like jaco did)
it's a wonderful piece of music and the important thing is the way you interpret it.
you can decide to play some part fast, some slow, play it as if the sheet is yours.
hope this helps.
