Johann Andreas Kellner (1724 – 1785) was the younger brother of Johann Peter Kellner. Under the tuition of his brother Johann Andreas became organist. As such he worked in Arnstad, Gotha and Leipzig. Besides organ, he learned to play the horn as well. Only a few works of Johann Andreas Kellner survive: a concert for horn and orchestra, a motette, and one Prelude for organ. The similarity of the Prelude with works by Johann Peter Kellner is striking. If Johann Peter had been indicated as composer, I would undoubtedly have believed it. It’s the only organ work we know of Johann Andreas Kellner. It’s a pleasant work that shows that Johann Andreas, much like his brother in similar works, was more interested in creating a sunny atmosphere than in writing counterpoint.
