The Symphony No. 42 in D major, Hoboken I/42, is a symphony by Joseph Haydn. The symphony was composed by 1771. It is scored for two oboes, two bassoons, two horns and strings.
The work is in four movements:
The first movement "is marked by the lively acciaccature that appear in the first bar." [1] Generally in this period the winds were tacet for the slow movement, and here they are silent at first, but they come in later. [1] The last movement has been described as a "novel use of the rondo form," [2] and H. C. Robbins Landon even goes so far as to call it a "characteristic Haydnesque rondo" and perhaps the first such rondo, [3] though others point out that it is not the sonata rondo that has come to be associated with Haydn. [4] Poundie Burstein has discussed Haydn's use of cadence in this symphony. [5]
