Claims

[Claims for Utility Model Registration] Performance means for causing a performer to play a piece of music; performance data storage means comprising a plurality of storage areas for storing performance data obtained from the performance means; and the performance data storage means. Performance time difference data storage means for storing, as performance time difference data, the time difference between the start points of each music part corresponding to each storage area when performance data is sequentially read from the arbitrary plurality of storage areas and automatic performance is performed; Performance data writing means for causing a performer to perform through the performance means and selectively storing performance data obtained thereby in an arbitrary storage area of the performance data storage means; and performance data for each of the storage areas. performance time difference data writing means for causing a performer to set time difference data and writing it into the performance time difference data storage means; and performance data in a desired storage area of the performance data storage means being sequentially read out from the performance data storage means for automatic performance. In that case, automatic performance is performed by delaying the timing when reading the first performance data from each storage area of the storage means based on the corresponding performance time difference data stored in the performance time difference data storage means. An automatic performance device comprising: automatic performance means;
