Score of Three Divertimenti and Alla Marcia for string quartet, lasting 12 and 3 minutes respectively. Originally titled Alla quartetto serioso, 'Go play, boy, play', Three Divertimenti was written in 1933 and revised substantially in 1936 where it received its premiere by the Stratton Quartet at Wigmore Hall. One of the original movements, Alla Marcia, was discarded and the material turned up some six years later in Les Illuminations. This original movement has been included in this publication due it's highly original and independent character.
