Divertimento for String Orchestra (Bartók) of imitation, fugato, and contains a three voice fugue. Bartók's Divertimento is scored for string orchestra: Violin I, II, Viola, Violoncello, and Double Bass, all of which contain divisi sections. Unlike the majority of orchestral scores, the minimum number of players in each string section is specified: 6 1st Violins, 6 2nd Violins, 4 Violas, 4 Violoncellos, 2 Double Basses.

Rostropovich later recorded the quintet with the Emerson String Quartet (12/1990) on the occasion of the gala concert celebrating the 125th anniversary of the BASF AG, Ludwigshafen. A few recordings of the quintet performed on period instruments exist, including a 1990 recording on the Vivarte label with the following lineup: Vera Beths and Lisa Rautenberg,
