Here I am again needing guidance and help with chord progressions. I am trying to teach myself and so far seem to be handling it quite well. Measure 8 with B# in the bass has me puzzled or could this be a chromatic step up to C#. Also measures 20 and 21 pose a challenge. I do not know what chords belong at these two measures. So many accidentals floating around. Your help would be much appreciated.
