Sonata for flute in D Major

Johann Gottfried Müthel (1728-1788) was a German composer and keyboard virtuoso. Particularly known as the last pupil of J.S.Bach, Müthel represented the "Sturm und Drang" composition style along with Carl Philipp Emanuel Bach.
Additionally, Müthel is considered as the first composer who used the term "fortepiano" in a published work as early as 1771 (Duetto für 2 Clavier, 2 Flügel, oder 2 Fortepiano).
Müthel was born in Mölln. His father was an organist and a friend of G.P.Telemann. After musical studies in Lübeck he served as court organist for Duke Christian Ludwig II in Schwerin.
In 1750 he become the student of J.S.Bach in Leipzig for three last months of Bach’s life and took over Bach’s duties for nine weeks after his death. Shortly after he mostly travelled: occasionally meeting and later maintaining lifelong friendship with C.P.E.Bach.
In 1753 Müthel moved to Riga (Latvia) where his first works were published. After working several years as a conductor of the private orchestra, he was appointed as organist to St. Peter's Church where he served from 1767 until his death in 1788.
