O pensamento sonoro-visual de Walter Ruttmann e a música de Berlim: sinfonia de uma metrópole (1927)

This paper discusses the original music score composed for the film Berlin: Symphony of a Metropolis (1927), directed by Walter Ruttmann (1887-1941). We try to understand the film's sound/music conception and its relations with Ruttmann's sound conception revealed in his texts. Our central objective is to observe and analyse the music of the silent documentary film and its theory, based on Ruttmann’s film and texts and the original score composed by Edmund Meisel.
