An automatic performance device includes a performance data receiving unit that receives performance data transmitted from a storage device without passing through a moving image distribution server, the storage device configured to store the performance data having a combination of performance information and time information, the time information indicating the time when the performance indicated by the performance information was carried out; a synchronization signal receiving unit that receives a synchronization signal by using an audio signal transmission path for an audio via the moving image distribution server; and a reproducing unit that reproduces the performance information of the performance data in synchronization with a video distributed at the time when the synchronization signal is distributed, at the timing corresponding to the time indicated by the time information and the time indicated by the synchronization signal.
