1. A performance apparatus comprising:
- a storage unit adapted to store a plurality of performance data and a plurality of beat position data, each of the beat position data indicating a beat position in a corresponding one of the performance data in terms of time;
a selection unit adapted to select any of the plurality of performance data stored in said storage unit;
a reproduction unit adapted to reproduce performance data selected by said selection unit;
a control unit adapted to control said reproduction unit such that preceding performance data being reproduced by said reproduction unit is changed over to subsequent performance data selected by said selection unit and performance data reproduction is continuously carried out without changing a tempo of the preceding performance data and a tempo of the subsequent performance data; and
a beat position acquisition unit adapted to acquire, from the plurality of beat position data stored in the storage unit, a beat position in the preceding performance data used for performance data reproduction before changeover controlled by said control unit, and a beat position in the subsequent performance data used for performance data reproduction after the changeover,wherein said control unit is adapted to control the changeover such that the beat position in the preceding performance data matches the beat position in the subsequent performance data without changing the tempo of the preceding performance data and the tempo of the subsequent performance data, and without inserting a stopgap phrase between the preceding performance data and the subsequent performance data, andwherein the preceding performance data and the subsequent performance data have different tempos.

Abstract
A performance apparatus capable of reproducing music pieces while making changeover between the music pieces without disturbing the rhythm of exercise, dance, or the like performed by a user to the rhythm of music. A beat position is acquired that will appear in a preceding performance data for the first time after a preparatory time required for changing the reproduction of the preceding music piece to the reproduction of a subsequent music piece elapses from when a music selection instruction is given. The reproduction of the subsequent music piece is started at the same time when the music is reproduced up to the acquired beat position.

4. A non-transitory computer-readable storage medium storing a program that when executed by a computer causes the computer to execute a method for controlling a performance apparatus including a storage unit, the method comprising:
-
a storage step of storing a plurality of performance data and a plurality of beat position data, each of the beat position data indicating a beat position in a corresponding one of the performance data in terms of time; a selection step of selecting any of the plurality of performance data stored in the storage unit; a reproduction step of reproducing performance data selected in said selection step; a control step of controlling said reproduction step such that preceding performance data being reproduced in said reproduction step is changed over to subsequent performance data selected in said selection step and performance data reproduction is continuously carried out without changing a tempo of the preceding performance data and a tempo of the subsequent performance data; and a beat position acquisition step of acquiring, from the plurality of beat position data stored in the storage unit, a beat position in the preceding performance data used for performance reproduction before changeover controlled by said control step, and a beat position in the subsequent performance data used for performance data reproduction after the changeover, wherein said control step controls the changeover such that the beat position in the preceding performance data matches the beat position in the subsequent performance data without changing the tempo of the preceding performance data and the tempo of the subsequent performance data, and without inserting a stopgap phrase between the preceding performance data and the subsequent performance data, and wherein the preceding performance data and the subsequent performance data have different tempos.
