Automatic performance device, non-transitory computer-readable medium, and automatic performance method

A non-transitory computer-readable medium, storing an automatic performance program that causes a computer to execute automatic performance, the computer comprising a storage part and an input part that inputs performance information, wherein

• the automatic performance program causes the storage part to function as a pattern storage part storing a plurality of performance patterns, and causes the computer to:
• perform a performance based on the performance pattern stored in the pattern storage part;
• input the performance information by the input part;
• detect a rhythm from the inputted performance information;
• acquire from among the plurality of performance patterns stored in the pattern storage part the performance pattern corresponding to the detected rhythm;
• and
• switch the performance pattern being performed to the acquired performance pattern.

An automatic performance method, executed by an automatic performance device comprising a pattern storage part storing a plurality of performance patterns and an input device inputting performance information, wherein the automatic performance method comprises:

• performing a performance based on the performance pattern stored in the pattern storage part;
• inputting the performance information by the input device;
• detecting a rhythm from the inputted performance information;
• acquiring from among the plurality of performance patterns stored in the pattern storage part the performance pattern corresponding to the detected rhythm;
• and
• switching the performance pattern being performed to the acquired performance pattern.
