Plato believed that music had an influence on the soul and can be either good or bad.  In ancient days, music was governed by mathematics, just like the heavenly spheres. This means that the same arithmetic proportions were found in music as in nature, giving music an influence on the soul, just like the stars were considered perfect. The music set to this text is found in The Wordsworth Dictionary of Musical Notations among other various books, but its origin is unknown.
