In its many different arrangements, Mozart's famous “easy sonata” has become a unique challenge to a variety of instrumentalists. This version for flute and guitar is a valuable addition to the classical concert repertoire for this setting. The Sonata K. 545 seems to have been literally predestined to the flute and guitar combination. There are many passages marked by the predominance of the melody over an evenly flowing accompaniment. And there are also many dialogue passages, e.g. in the first movement or in the canonic entry and exchange of parts in the final movement, which can also be convincingly depicted on two instruments. Moreover, the tonal ambitus of the original is such that only few octave transpositions are required. The present arrangement closely follows the piano version so as to preserve the original sound constellation as much as possible.
