Who is the author of Flohwalzer?
Flohwalzer is a simple piano piece, often one of the first learned because its fingering is simple and it allows beginners to perform a piece that is harmonically and rhythmically pleasing.
Despite its name, the piece is not a waltz in triple meter, as it has a time signature in duple meter. The composer is unknown. A book by Eric Baumann attributes the piece to Ferdinand Loh, but this is obviously a joke ("F. Loh" = Floh, flea in German). The piece is notated in the key of G-flat major, because most of its notes are played on black keys in those keys, makes the fingering easier.
