Decidedly, we haven't heard anything yet from Renoir, as Sur un Air de Charleston is a silent short film. There is surrealist dream logic in the drawing of the phone which then becomes real, as well as Dadaist elements like the slipping on the waxed ground. It is another effort by Renoir to play around with the medium... but perhaps something else is at the heart of the matter. The film hails jazz culture as being timeless and universal underscored by flipping colonialist stereotypes on their head (the white cannibal, the black space explorer/time traveler). There is a theme of savagery that runs through the film that I consider to be extremely tongue-in-cheek. I conjecture that the film was an homage to the Jazz Singer in many ways - perhaps not that particular film text per se, but more generally the hype that would have existed in the industry at the time about the shift to sound and the potential of films like the Jazz Singer to accomplish the feat. It is difficult to deny that Sur un Air de Charleston requires sound for the pleasure of spectators at the time (ironically there were none), but equally undeniable that the sound should come from a synchronized soundtrack. I simply feel this way because of the manipulation of the dancing through editing where Renoir presents the dance in three or more temporal states. It feels to me that Renoir was imagining sound techniques prior to their industrial application. Why not release the film at the time then? My two answers are that Renoir would have been unsatisfied with the anachronistic homage (the film was silent) and that he may not have sought to offend many of his filmmaker colleagues who would soon be reeling against the introduction of sound film.
