The practice of jazz is one of the most popular manifestations of popular music in Chile. The most regular tracks appear towards the 1920s around the figure of the composer, violinist and researcher Pablo Garrido, manager of the first ensembles and local jazz orchestras. From 1940, a new generation of young musicians aligned themselves with jazz improvisation beyond the predecessor jazz, which they considered commercial, baptizing it hot jazz. This would result in the founding of the Club de Jazz de Santiago in 1943 and the formation of the first national all-stars, The Chilean Aces of Jazz, in 1944 and 1945.
