• In this paper, we report about a creation of art that consists of two ferrofluid sculptures that moves synthetically to music. The two spiral towers stand on a large plate that hold ferrofluid. The body of the tower was made by a new technique called "ferrofluid sculpture" invented by Kodama, which enables artists to create dynamic sculptures with fluid materials. This technique uses one electromagnet, and its iron core is extended and sculpted. The ferrofluid covers the sculpted surface of a three-dimensional iron shape that was made on an electronic NC lathe. The movement of the spikes in the fluid is controlled dynamically on the surface by adjusting the power of the electromagnet. In this work, we tried to activate fluid precisely by utilizing digital music metadata. To control the synchronization of the ferrofluid with the music playback in real time, time series metadata are added to the music beforehand. The metadata consist of musical information, such as beat position, chord progression, and melody block information, and ferrofluid control information such as DC bias voltage and AC pattern. Each data record has a time stamp that indicates the timing of presentation. All data are stored in time-series order. These time series metadata must be accurate for precise control of timing, so as to cancel the time delay of fluid movement. By this correction, the time when the protuberance of the spike reaches its maximum size is coincident with the beat of the music. As a result, the rhythm of the fluid movement coincides with the musical rhythm.
