F.A. Rösler (Antonio Rosetti), a Bohemian by birth, worked as court music director in Ludwigslust/Mecklenburg. He wrote 14 flute concertos altogether the most important of which is the concerto G major, Op. 14. The expanded head movement combines the sonata form with the ritornello technique of theconcerto grosso. Right at the beginning, the basses of the "Mannheimer-Walzermotiv" make it clear that Rösler knows how to use effectively the orchestral technique of his time. Despite all motivic and thematic as well as harmonic abundance, Rösler achieves in this concerto an almost natural musicalunity.
