We may well though ask whether it is not for its composer rather than its auditors to "say" more about it? Compare a) the number of comments made by so many other people upon Brahms's fourth symphony with b) the remarks Brahms himself made or did not on the subject. Yet to which would one turn or go? And why?
Probably not to Brahms, since much of the creative process is done by the subconscious, and it would not be strange if an academic actually had better insight into the structure of Brahms's fourth symphony than Brahms himself. This is one of the reasons for the existence of so much dull music, in that you get student composers who read these structural analyses and imagine that it's all thought out by the composer. So they laboriously try to recreate similar schemes in their own music, and the result is tedious and uninspired.
