Don't know all of it but the beginning is simple enough for me to get.
Bass Run= Ab, Bb, Db, Db (play a Db chord 2nd inversion (Ab, Db, F)when u strike the last D)
Ab, Bb, Ab,Gb, Gb (play a Gb chord root position(Gb,Bb, Db) when u strike the last 2 Gb's)
play the first bass run and chord over
Bb, Ab, Gb (play the Gb chord again when striking Gb on the bass)
hope this helps. you basically bounce between those 2 chords with that bass line for most of the song u can change the inversion of the chord to your liking i also like to add the ninth, and maybe throw in the 7th on the Db. be blessed
