The Kreisleriana is quite a story as told here
I love the story about Robert Schumann and his sense of humor. In his Sonata No.2 in G Minor Op.22, he gave the following instructions for the performer. "So Rasch Vie Moglich", i.e. as fast as possible. Then later in the same movement he instructs "Schneller", faster and again slightly later "Noch Schneller", still faster. That is my kind of guy.
But, forget about all that for now... here is the Schnell und Spielund from Opus 16, the Kreisleriana.
