Link to Havona_Bass_Solo_TAB.pdf
This is the TAB of the bass solo part of Havona from Weather Report's album Heavy Weather, which I have transcribed note for note.
Jaco's music is all really cool, but this one is particularly moving, and the beauty of the bass solo is perfect, so please try practicing it and experience the perfection.
You can also use the tab to study phrases. And the tab is written in the positions that Jaco probably played so you can learn how to play it beautifully.
