Written by a young Mozart in 1772, the three divertimenti commonly known as the Salzburg Symphonies are works that bridge two common forms - the divertimento of the time and the Italian symphony of the time. While the true divertimento of the time was 5 movements, these works are each three movements in length, as was the Italian symphony of the time. These works are light-hearted and less demanding on the players than many of Mozart's later works. Today, the are performed either by string orchestra or by string quartet.
