Yet this most fundamentalstandard of historical periodization conceals a host of paradoxes.Nearly every movietheater, however modest, had a piano or organ to provide musical accompanimentto silent pictures. In many instances, spectators in the era before recordedsound experienced elaborate aural presentations alongside movies' visual images, from the Japanesebenshi (narrators) crafting multivoiced dialogue narratives to originalmusical compositions performed by symphony-size orchestras in Europe and the United States
. In Berlin,for the premiere performance outside the Soviet Union of The Battleship Potemkin, film director Sergei Eisenstein workedwith Austrian composer Edmund Meisel(1874-1930) on a musical score matching sound to image; the Berlin screenings with live musichelped to bring the film its wide international fame.
