Caprice no. 9 is straightforward, lighthearted, and fun. I found it tempting to take a quick tempo, but was always pulled back by the tricky fingerwork starting at m. 16, followed by the demands for rhythmic precision at m. 19.
Obviously, the performer must figure out a scheme for dynamics, since no direction is given. You can listen to my ideas in the recording, but I also encourage you to experiment on your own!
