Bass teachers don't fully understand resolution and so it might be difficult to find one to teach you this. But a jazz pianist, guitarist, or sax player can explain it perfectly to you. Also, jazz upright bass players understand resolution as it plays a part in how a great walking line is performed.
Oh, P.S. The bass line that was played was played on a F7 chord going to a Bb chord. The bass player played on the D string, a third fret F down to a first fret Eb and finally an open D before playing a first fret Bb on a Bb chord. Had he substituted the open D for an open A and then played the Bb first fret note, he would have had a logical and musical resolution the moment that he played the Bb note.
