Divertimento (from italian divertire - to amuse) is a music genre, with most of its examples stemming from the 18th century. The mood of the divertimento is most often lighthearted (as a result of being played at social functions) and it is generally composed for a small ensemble. As a separate genre it appears to have no specific form, although most of the divertimenti of the 2nd half of the 18th century go either back to a dance suite approach (derived from the ’ballet’ type of theatrical divertimento), or take the form of other chamber music genres of their century (as a continuation of the merely instrumental theatrical divertimento). This was arranged from Mozart’s Divertimento for wind ensemble for Saxophone quartet.
