The title may be read as an indication of the key and genre, on the one hand, but also as an allusion to a slightly depressive mood, on the other hand. Mozart's Piano Sonata in A minor which may have been created in the Parisian street mentioned in the subtitle virtually serves as background for this little, yet somewhat tricky piano piece. There are no direct quotations, but the dissonant chord from bar 2 of the sonata in A minor hovers in the background. Mosaic-like, slightly dabbed sound elements are regularly interrupted by brief, strong beats. Ambitious performers who want to explore new playing techniques will enjoy this piece as much as the audience.
