The Sonata in F Major by Johann Joachim Quantz, arranged for three clarinets by Matt Johnston. Born in 1697, German flutist Johann Joachim Quantz was a prolific composer of the late Baroque period, having written hundreds of concertos and sonatas during his lifetime. He assumed the role of teacher, composer and flute maker to the court of Frederick the Great of Prussia in 1740, a position which he held for over three decades until the end of his life. This Sonata in F Major, originally composed for three flutes, is quite unique, in that he composed it in a manner that the parts frequently alternate between soloistic and accompanimental figures. It is in three movements: Vivace, Largo, and Moderato.
