In 1787 Rembt published 12 Trios for organ. Manuscript Ec 268.5, held by the Universitäts- und Landesbibliothek, Bonn, contains 6 of these 12 Trios.The last of these six is a trio in E flet major. In my opinion it is the most beautiful of the six and the best written one. The main theme of the trio is not only for the hands, but the feet get their turn in playing the main theme as well.
