When searching the internet fore sources for music by Kehl, I came across “The Wöchentliche Nachrichten und Anmerkungen die Musik betreffend”. This journal appeared weekly in Leipzig from 1 July 1766 to 24 December 1770. Most of the eight page issues contained one or two main articles, usually published in installments, followed by short reviews and a piece of music. It was in one of the issues of this journal I found the piece I posted two days ago.
Johann Adam Hiller (1728 – 1804), the editor, initiator and almost sole contributor to the WNA, was, at the time of the journal’s publication, conductor of the “Großes Konzert” in Leipzig (later to become the concerts at the Gewandhaus). According to his introduction in the first issue, Hiller intended his journal for the musical dilettante and hoped to assemble in the journal what could later be seen as a history of contemporary music. Because of WNA’s mixture of essays, music reviews and musical correspondence, it is seen by many as the first forerunner of the Allgemeine musikalische Zeitung (1798-1848) which came to be viewed as the model for nineteenth-century general music journals. Later in life Hiller became Thomascantor at the Thomasschule in Leipzig and organist in the Neukirche.
Besides the piece by Kehl, Hiller published some more organ pieces in his journal. The piece by Kehl, and another one by Wolf indicate their composer’s name. But the others give no reference to who the composer was. Since Hiller was an organist and composer himself, I suspect these pieces were written by Hiller. But I can’t be sure, hence the question mark.
