hey. i need a little bit of help.

i had to do a music assignment for my friend and play bass on a fear of the dark cover. but no matter how hard i tried kept getting lost toward the beginning of the solo.
so ive been thinking what can i do instead of play what steve harris does?

soemthing like a riff, that repeats and moves around the Dminor triad. would that be alright?
if anyone has any ideas for a riff to play diring the soloo be good to see (tab?)

or anything else?
My red is so confident that he flashes trophies of war and
ribbons of euphoria
you could just make it really easy and play root notes. that'd probably sounds the best.
