The first question that comes to the mind of the intelligent person is: "What is it in color and in sound that appeals to man?" I will answer: "It is the tone and rhythm of color, as well as of sound, which have an influence on the tone and rhythm of our being." Our being is our capacity for the resonance of tone and rhythm that comes from sound and color. This capacity enables us to be influenced by sound and color. Thus, some have a liking for a certain colors others have a liking for another color. In the way of sound, some are attracted to a certain kind of sound. In the form of voice, some are attracted to the baritone or bass voice, others are attracted to the tenor and soprano. There are some to whom the deep sound of the cello appeals; there are others who are interested in the sound of the violin; some can enjoy even the thick sound of the horn and trombone; others can enjoy the flute. What does this show? It shows that there is a certain capacity in our hearts, in our beings, and it depends upon that particular capacity what kind of sound appeals to us.
