I've been using Bach Inventions and Sinfonias for the past year or so as a daily technical exercise. I spend about an hour each morning working slowly through challenging sections of the music. After about two weeks I record a performance and post it to my YouTube channel. The goal of these videos is to track my progress and growth over the course of studying J.S. Bach's counterpoint. I do not consider myself a professional classical pianist but I still hope you enjoy my best (albeit amateurish efforts) at performing Baroque music.
Check out my reasoning for practicing Baroque music as explained in this previous blog post.
