From among the nearly 300 flute concertos by Johann Joachim Quantz, the flute teacher of King Frederick the Great, the G-major work QV 5:174 has been enjoying a very special popularity ever since its rediscovery by the Dresden flautist Moritz Fürstenau in the late 19th century. The principal source for the present Urtext edition is the set of parts of the first performance which took place in Berlin's Charlottenburg Palace in 1745. This source assumes a unique significance due to the many entries and emendations in the hand of the composer.
