I've been studying counterpoint for years now, learned mainly from Fux's gradus and developed a solid understanding of species counterpoint. That said, one quick analysis of this first movement will reveal deviations from the rules presented in that book. Accented passing notes, leaping from dissonances, and the occasional unprepared chord in second inversion, that one consecutive fifth... I'm well aware of the rules broken and the liberties I have taken when it came time to make the transition from species exercises to actual composition. Despite that, i'm very proud with what I ended up with. There's plenty that I wish to improve, and hopefully you'll get to hear the results of my efforts in the following 2 movements, as well as in everything that will be released following the completion of this sonata.
