But you have forgotten to mention one of the most important characteristics of music: timber - tone quality. And that is also expressed in physical terms, but the combinations are limitless. It is timber that distinguishes the sound of a clarinet from a violin even though they may be playing the same pitch and holding that pitch for the same length of time. Should I assume that your metamusic would attempt to go beyond even this? Mimi
