Communication and Commonality

Common in any Communication are that a phenomenon is recognized as functioning as Signal, and the meaning of the Signal.  Hence, Commonality in Communication is a function of those involved. For example, a thumbs-up or a green light may be more common than the word "Go!", or the word "Allez!", i. e. they are signals the meanings of which are more widely accepted than those of those two words.  Furthermore, in some ideologies, any Art functions as a provocation to Action, while in others, it provides passive entertainment.  Plus, apparently escaping even Nietzsche's notice is that while the opening notes of the Dithyrambic chorus might be a signal to Dionysian celebrants to begin an ecstatic dance, such a response to one of Wagner's pieces would likely get one escorted out of a concert venue.  So, in contrasr with either Nietzsche's implication, in #810 of the Will to Power collection, that Words are more "common" than Music, or its contrary, Commonality is not an inherent property of one medium as opposed to another.  Rather, it is established only by those involved in Communication.
