A divertimento is a piece of music which is lighthearted and easy to listen to. It is often performed on social occasions, e.g. as music to be played while people eat, or as after-dinner music.

The divertimento became popular in the 18th century. They were played by a small group of instruments. Mozart wrote several pieces called "divertimento". They are similar to a serenade. A divertimento often has several movements, e.g. six, seven or more.
