I download the concerto KV207, 52 pages. When I can play the No 5 (20 pages), any concerto seems to be easier for me to play. Recently, I watched the famous Japanese movie of orchestra, lover and dream. It really gives me much inspiration. No one can play well without effort. In the process of practicing, you can feel the sense of exist.
Every moment, every note, you can feel the movement of mind. It is real!
