I'm cycling or I'm practicing Beethoven's shortest Sonata, Sonata No. 25 op.79. I've been practicing it for eight years everyday. It has three movements. I've got the second movement down pretty good. The third is coming along too. The first, the Presto alla tedesca, is the most challenging. But others have mastered it, and so will I given enough time. Fingering, flexible ring fingers and a whole lot of hours practicing is key. Andy Cinnamonbear seems to have accomplished that. Note the notes his teacher has written on the music. They are the same notations I've made on mine as I have struggled to teach myself while waiting for paint to dry.
