A musical argument is a means of creating tension through the relation of expressive content and musical form: Traditional dialectal[a] music is representational: the musical form relates to an expressive content and is a means of creating a growing tension; this is what is usually called the musical argument.Experimental musical forms may use process or indeterminacy rather than argument.
[2] The musical argument may be characterized as the primary flow and current idea being presented in a piece: The very definition of musical argument is something that keeps going, and you uncover new details and new combinations.
A verbal argument implies that there's [sic] two sides; a musical argument makes the two sides one thing, like counterpoint.
A fugue is like that; a double fugue, at least, takes two different ideas and shows you how they relate, and it shows you how they're the same thing.Thus one may hear of a musical argument being interrupted, extended, or repeated.
