Les Synthétistes were a group of Belgian composers whose goal was to synthetize the modern musical tendencies starting in 1925. All of them were ex-pupils of the Belgian composer Paul Gilson and started the organization as a way to celebrate their teacher's 60th birthday in 1925. Their first act was to publish the magazine La Revue Musicale Belge. The group longed to be a Belgian counterpart to the famous French composing group Les Six.
