Some years ago I researched Bach cantatas where all movements are based on a single hymn tune or chorale, but I've since lost track of that work.
If I remember quickly, there were 10 (or 12?) cantatas that are like this - no recits or arias, just movements based on a single hymn tune.??
BWV 137 and 192 come to mind.? Is there a quick way to find the others -- or perhaps someone knows this offhand?
We are performing BWV 137 (Lobe den Herren) next weekend, and I'd like to include a brief comment on this particular form of Bach's cantatas in the printed program.
