ok I will write it out how I play it on the board (LH/RH), first chord is Bb/Ab C Eb next is Eb/Ab Db F then back to the Bb/Ab C Eb then walk Eb/Ab Db F, Dd/Ab C Eb, C/Bb Db F#, B/Bb Db F#, /Ab Db F, Bb/Ab C Eb hope this helps if you have any other questions do hesitate to ask, but try to work your own bass line in there, experiment a little that is what this site is all about peace!
