In the Classical music period the serenade became a piece of music for a small orchestra or a group of several instruments. They are similar to a symphony but lighter in character. They are often the same as a divertimento. Mozart wrote several serenades of this type, e.g. his famous "Eine kleine Nachtmusik". Later composers such as Brahms also wrote orchestral serenades. Other Romantic composers often wrote short instrumental works which they called “serenades”.
