The Symphony No. 38 in C major, Hoboken I/38, is an early and festive symphony[1] by Joseph Haydn. The symphony was composed some time between 1765 and 1769. Because of the virtuosic oboe parts in the final two movements, it has been suggested that the work's composition may have coincided with the employ of the oboist Vittorino Colombazzo in the fall of 1768.[2] The symphony is popularly called the Echo Symphony, a nickname that, like all other named Haydn symphonies, did not originate with the composer.
