Abstract
A sound generation control apparatus displays in a loop region a music data image corresponding to music data to be generated as time progresses, such that progression of the music data corresponds to a lengthwise position of the loop region. The sound generation control apparatus outputs time information indicating the time that progresses from a start of generation of music sound. The sound generation control apparatus controls the generation of the music sound based on the music data according to a relationship between a lengthwise position of the loop region and a displayed location of the music data image in the loop region. The sound generation control apparatus displays a plurality of the music data images in the loop region, and simultaneously generates a plurality of music sounds corresponding to the plurality of the music data images as the time progresses.
