Computer dynamic posturography (CDP) tests will provide stability scores in volunteer subjects who have had no previous history of falls or vertigo. Subjects will be randomized into several different music listening groups and one control group. Examiners will be blinded as to the music listened to and the outcome measurements. Subjects will be blinded as to their posturographic measurements. The music listening groups will be given a daily specific music listening task. CDP tests will be obtained 10 minutes, 1 week and 1 month after subject's treatment. Music selection will include Mozart, Nolwenn Leroy and others suggested to change human stability.
