Ruppe was a German who settled in Leiden, the Netherlands, and I like to call him our Dutch Mozart. He composed a large variety of music.
This is from his collection "Dixhuit Pieces pour l'Orgue our Piano-Forte" (ca. 1800).
I apologize for the somewhat imprecise playing,. I fell down a few weeks ago and am still slowly recuperating from severely twisted muscles in my left leg and back.
