Abstract
A performance apparatus capable of reproducing performance data having a desired tempo, even if performance data having the desired tempo is not present in a play list. In a search, a main point value indicated in each of meta data in music information files respectively corresponding to pieces of music registered in the play list is compared with a target tempo value. If the main point value falls within a range in which main point does not vary more than plus or minus 3% from the target tempo value, the music whose main point value is currently compared with the target tempo value is determined as intended music. If the intended music is not present in the play list, music data having the target tempo is automatically produced and reproduced.
