Manuscript Am. 386, owned by the Staatsbibliothek Berlin contains some 20 chorale preludes by Johann Philipp Kirnberger. And one by a certain “Mademoiselle Grunow”. It’s probably not a coincidence a collection of works by Kirnberger contains one work by this Mademoiselle Grunow. But it remains a mystery who she was or what her relationship with Kirnberger was. Other than a reference to a second work by her hand I can not find anything about her.
But the piece itself is simple, yet charming.
The recording was done on the sample set of the Holzey organ of St. Peter and Paul in Weissenau by Prospectum.
