The last of the Eight Humoresques, Op. 101, by Dvorak.
I have to say that this was my least favorite of the set, and it also didn't really dazzle my teacher. The initial statement of the melody is buried, and the middle section (which appears unrelated to the beginning and end) has some of the kludgiest writing I've ever played. As for the ending, to quote my teacher, "what's with that?!"
However, it's been mostly fun to play these, and some of them are real gems. I have even come to sort of like #7.
