As can be seen, it seems difficult to speak of language without speaking of meaning, and cyclically on this forum the same old specters seem to re-emerge. Regardless of how everyone wants to see it, I take the liberty of recalling some historically relevant concepts, even if perhaps already done in past discussions. If someone has the patience to read them, and if they do not already know or remember them, perhaps they can find some food for thought.
Formalism in music finds one of its past champions in Hanslick. However, the concepts of language, sense, and meaning have been addressed more completely by logic and linguistics. As already stated elsewhere, and to not go too far back in history, Frege distinguished between Sinn and Bedeutung. What are they? Let's make a couple of examples (they are not the original ones): the various road signs indicating direction and distance from Rome are each a different Sinn towards the same Bedeutung: Rome; the 216th Pope of the Catholic Church or the son of Giuliano della Rovere born in Albissola in 1443, are two different Sinnen that indicate the same Bedeutung. There are at least two things to note here: first, that Sinn is the "mode in which the object is given to us"; second, that a Bedeutung has many Sinnen, while a Sinn generally has only one Bedeutung. For Frege, the field of application of this theory is language, which he essentially distinguishes into natural language and logical language (with two truth values). In this way, Frege can say that "Ulysses landed in Ithaca immersed in a deep sleep" is a sentence with a Sinn but whose Bedeutung is uncertain. For Frege, if an expression contains a term lacking Bedeutung, the entire expression is neither true nor false, meaning it is itself lacking Bedeutung, even if it has a Sinn: this is essentially what Hanslick thought of music.
It is a fact that shortly thereafter Russell communicated to Frege that this theoretical approach leads to an antinomy and in his essay "On Denoting" actually replaces the notion of Sinn with the concept of "propositional function." In short, for Russell, an expression can have meaning even if it is composed of terms that individually denote nothing. Otherwise, following Frege and his example of Ulysses, we would have to conclude that the entire Greek epic lacks Bedeutung, which in Italian (and I say this only now on purpose) translates as meaning. It is, in my opinion, worth noting that initially in English Bedeutung, if I am not mistaken, was rendered as reference and later as meaning. Furthermore, Sinn can also be translated as meaning, just like Bedeutung. In some way, then, the notion of Sinn without Bedeutung is a misleading notion, and it becomes so especially in the Italian translation. Hanslick is actually prior to Frege and his formalism is somehow autonomous from him, even if it becomes quite easy to read him through that conceptual framework. Hanslick, in open opposition to Wagnerian aesthetics, removes all content from music, including the sphere of emotions. Music has many Sinnen, but no Bedeutung: this is essentially the formalist position and changes little even in its "enhanced" version, such as that proposed by Kivy. In Kivy, the semantic value of music is still denied, but the existence of a relationship between music and emotions is strongly revalued. Moreover, Kivy admits that the lack of content is limited to Western instrumental music, while admitting that music can be significant, even Western music, when accompanied by words. This expanded formalist position alone should raise concerns among its supporters: how indeed could music be significant when accompanied by words if it cannot be significant on its own? Either the meaning is only that of the words and therefore music adds or modifies nothing, or music itself must have some potentiality. In any case, obviously, any formalist finds themselves forced, for better or worse, to deny music the status of language: if music has no content, then it cannot be a language, since a language is a conventional set of organized symbols suitable for communicating or expressing something. This position, in my opinion, derives precisely from the initial misunderstanding brought by the Fregean distinction and the consequent induced antinomies.
Obviously, the formalist position is not the only one. From Wagner onwards, passing through Adorno, to arrive, each in their own way, at Wittgenstein's "Philosophical Investigations," to the hermeneutic tradition, cultural studies, gender studies, and even to numerous exponents of analytic philosophy (Danto, Levinson, etc.), today believing that the asemanticity of music is the only doctrine is at least naive. Even neuroscience, for a few years now
they would claim to have demonstrated that music promotes meanings in a manner analogous to other languages (if anyone is interested, perhaps I can find some excerpts from these studies).
What should we actually mean today when it is said that music has many senses and no meaning, given that people insist on using such a proposition? If it is not to remain a formula learned from someone or read somewhere, one should be able to justify it. If it is understood according to the notions of Frege (and Hanslick), it risks appearing to be a true misunderstanding. Indeed, what would be the many senses of a piece of music? As Sinn [sense], sense is nothing but an expression, a way of saying something; therefore, as Sinn, every piece of music should have only one sense, or rather should be "a" sense, not a multiplicity, unless by sense one means a performance—not that which is given by a performance, but the performance itself—but then one would move even further away from an explanation.
What other connotation could be given to the term sense, perhaps that of spoken language? In the Italian language, if I say "Pippo è un cane" [Pippo is a dog], someone outside the context can quite easily ask me "ma in che senso?" [but in what sense?]. I might indeed have indicated a dog named Pippo, or addressed my friend Pippo disparagingly, or even reminded someone that the namesake comic character is a dog. His question can therefore be easily replaced by "what are you referring to?" In Italian, therefore, a content toward which the sense of an expression refers is somehow presupposed, so much so that in common language (and not just Italian), sense and meaning are easily interchangeable. To think, then, that the many senses of music should be read in the connotation of spoken language cannot again explain the issue.
We could proceed at will, and there are indeed numerous semantic models, too many even, but the fact is that we are nonetheless dealing with a reality that we want to describe in some way, and to do this it is necessary that we establish terms that are effective for the purpose. In itself, there is no problem in calling sense 'meaning' and meaning 'reference' or vice versa, but in the end, it is the description as a whole that must hold up as well as possible, even if it will always be only an approximation. Perhaps it is therefore worthwhile to recover at least in part Russell's objection to the use of the term Sinn, whether used by Frege or by Hanslick. Or perhaps one could also acquiesce to the suggestions of Wittgenstein who, in addition to contesting the validity of reference theories, also opposes the very idea of the possibility of "pure" music: to understand a musical work, we use categories that we derive from non-musical experiences (and thus musical understanding and expression are not closed).
These are all things already said. The only thing I can emphasize is that before apodictically pronouncing this or that conclusion, it would be better to ask oneself some questions and have some doubts, of the type, in no particular order:
-what interpretation can I give to something that has no meaning?
-what connotations can be had for the terms language, sense, and meaning?
-does language come first or does meaning come first?
-if meaning is a sign of something outside the signifier, must this something necessarily be univocal and determined?
-if sense is the way in which this something is indicated, in what way is it possible to indicate something that does not exist?
-to have a semantics, must that which is indicated be unitary or can it be multiple?
-could the way of indicating something itself be something?
-can there exist an expression of thought devoid of content and full only of form?
-etc. etc..
