Opus 1, Nr. 5, Sonata III, just one of the eight sonatas, was introduced by Bettina Kiefner
into Blue Monday
sometime in 1995 but was not too popular. It has five movements and comprises a Marche, Adagio, Allegro, Air Largo and Gigue Vite. It is fairly straightforward baroque stuff which can readily be played by medium proficiency players.
