Resynchronize Japanese "Geisha" Dance Video Using Music of Different Styles

Abstract

Music and dancing are two different arts yet inseparable and which can be both powerful expression channels for a society or an artist. In most cases, the rhythm, tempo and performance of a dance depend on those of the music. This paper presents a new form of artistic expression form of the Japanese "Geisha" dance video that combines music and dancing in a different manner than the ones we are used to. With a selection of different kind of music, it is now possible to have one type of dance that synchronizes with all those music genres, independently on the order in which they are played. By taking as input a series of various audio music signals, the system performs the retrieval of spectral shape features, by locating signal peak position and detecting the onsets. With the information gathered, a scalar factor is deducted and used as a multiplier to change the speed of the dance video stream playback. (Abstract)
