As far as the history of music is concerned, the First World War did not mark a significant turning-point. This had occurred several years earlier with the advent of atonal music, and for many contemporaries it was this that represented a major catastrophe of a different kind. What the war marked was rather a sharp drop in the production of music, with hardly any really great works being written. Musical life was also adapted to war service within a very short time, and especially at the beginning of the war, when composers and performers were meant to make their contribution to mobilization, their productivity was considerable. What innovations there were resulted primarily from technical developments and the consequences of the war.
