Abstract
MIDI based pacing music was made. This auditory stimulation gave cue and pace to locomotion. MIDI based pacing music which drum-bass part was strengthened beat, was compared with MIDI music without drum-bass part and clicking sound of metronome. And clicking sound of metronome was clearest. Pacing music which drum-bass part was strengthened beat was effective, when the information of pace is reflected in gait. And it can sustain concentration of the subject longer than monotonous clicking sound of metronome.
