Johann Friedrich Franz Burgmüller, generally known as Friedrich Burgmüller was a German pianist and composer during the Romantic period. He is perhaps best known for his three collections of children's etudes (or "teaching pieces") for the piano, particularly his Op. 100 "25 Études faciles et progressives" (25 Easy and Progressive Studies) for early intermediate students. The other two collections, for more advanced students, were Op. 105 and 109.
