||Manuscript, n.d.(1st half 19th century)
||Alleluia in D major
Related to/actually composed by (though perhaps copied in Mozart's hand- there are many examples of this; Alfred Einstein has some interesting and thoughtful things to say (about Mozart as a student of others' work) in his book, btw...) a Halleluia by "Kunzen" (which Kunzen ? Either FLÆ Kunzen as suggested by RISM, or his father Adolph Carl Kunzen (1720-1781), or grandfather Johann Paul Kunzen, perhaps). It is not, near as one can tell, an original work by Mozart.
