I just created a workpage for this piece. The alternate title on the workpage, which describes the work as a Cantata, was on the title page of the original score, although that page is not included in the pdf of the score. I will be happy to tag the work if no one does it first; this post is just to call attention to the Cantata designation for whomever does the tagging.
BTW I apologize for my absence the past few months from tagging. I do intend to resume helping after I've finished uploading my mother's works
