I don’t think musical thought is “in the mind” at all, it’s all “out there”, in the artifacts deemed properly musical (recordings, performances, technologies) but also in the howling of wolves, the shifting moods of the sky, the dragons in the river, the gifts of the rain gods, – and once again in the little, spontaneous acts: the “let’s try this” patching of an oscillator to control its own frequency, the bits of buggy Max code that do more interesting things than the intended purpose… all of this can be thoughts within music.
Sadly, throughout much of human history, we have removed “thought” from its proper place in the world and dictated that it be strictly confined to the mind, in the form of “mental representations” that we then force upon the world. The broader context is that of servomechanism, of the “closed loop” which reduces the world to only that contained in the representation: I try something, compare my observation of result with my internal representation, and adjust accordingly. Agency becomes a fixed will imposed on the world, not the freedom to open oneself to the world, to work together to bring forth a mutual destiny.
Yet anyone who has climbed a mountain still recognizes the extent that we dwell in a world and yes, use every aspect of this world along with our bodies and minds as devices with which to think.
Some of this can be blamed on language, but not really. Language is also exteriorized. We define signifiers (words) only in relation to other signifiers (words). They circulate in a play that is sometimes fixed and sometimes free. One does not need to posit the signified, the hidden “idea” or “intent” within the mind. Simply follow on words with other words. We seem to do alright…
This reductive image of thought is not based in the human but in Man; one side of the artificial (Man/Nature) divide that passes through the human, and critically so.
A “mental representation” is simply a set point in a servomechanism that helps Man command Nature to use. In the initial positing of the tool, it was not needed. For millions of years, human ancestors evolved sophisticated stone tools through a set of socially-coordinated gestures, well before the origin of speech or any other evidence of thinking at a distance. The thought that went into the tools simply stayed there, in the form of the tools, and in the gestures that made them. It was not encoded anywhere as a design or plan.
However, in the perfection of the tool (motivated by co-evolutionary pressures, not yet any conscious plan, certainly not a consciousness of “servomechanism”), a servomechanistic conception nonetheless emerged. This falls out naturally from control theory, specifically the “linear quadratic regulator” (LQR): if I’m going to drive a state to zero with minimum (squared) error using a minimum (energy) input; i.e. extract the most from Nature using minimum effort, the optimal configuration introduces feedback; I make the input a function of the state (which I estimate using the output). This is the same configuration that operates a thermostat or that we use when we drive a car. So of course humankind had to evolve the thought-“of”; the set-point of the servomechanism, in order to optimize the tool, in order to extract the most from Nature using the least energy. This became what we call “mind” and precipitated the divisions that we now take as commonplace: subject/object, mind/body(world) and so on.
Thus was born the thought-“of”. Unfortunately, it requires a [transcendentally] constituting subject, a definitional structure of ‘givenness’ through which music is given. The human animal, like the wolf, does not require such givenness. She remains within immanence, producing acts that are consubstantial with thoughts, thoughts liberated from their confinement within a servomechanism called “mind”.
The liberation of music from “mind” appears when the human ceases to be Man, and becomes the animal he always has been.
