41 in C major, Hoboken I/41, is a festive symphony[1] by Joseph Haydn.
It is scored for flute, two oboes, bassoon, two horns, two trumpets, timpani and strings.
[2] The work is in four movements: The flute appears only in the slow movement where it is featured prominently in several elegant solo passages.
Using that type of solo usually would seem out of place in the classical symphony.
He felt the complete freedom to innovate as he wished, as he was composing in the relatively isolated palace of Eszterháza.
