Most courses for writing walking basses focus on 4 bass notes for one chord, where in general the pattern is (chord - maybe chord - chord - passing tone). However, there are also some pieces with half-note chords (and where I would still want to write a quarter-note walking bass, because using eighths would be too frenetic), leaving only 2 bass notes for each chord.
How does the theory change for a half-note chord sequence? What I wrote up to now was an adaptation of the 4-notes-per-chord style (chord - passing tone, chord if possible), but this is obviously more constraining and makes me write more repetitive basslines. Maybe I should relax the constraint of the 3rd beat being a chord note (or allow second inversion)?
edit: as I guessed, this question is too broad - thanks to both replies. Can anybody point me to examples of this technique?
