I would've read this short-story either in 2019 or 2020, possibly in a sci-fi compilation.
The Gist of the Story goes as follows: The Protagonist, A Human (possibly a diplomat of some kind), arrives on a plant (potentially Mars) to meet with members of the resident civilisation (Martians). This Species, who I think were humanoid, share similar senses to Humans, all but for a smaller range of experience for either sight (colour-blindness) or smell.
However they also have a sense that Humans do not, which is the ability to "perceive sound/waves", and so have created instruments which produce "visual music" which they view. The Diplomat overhears of this experience, and presses the Alien Diplomat that he has been meeting with to witness the phenomenon. The Alien Diplomat warns him that, although humans can experience this phenomenon through (some means that I can't recall; possibly through injection of a drug), these means, in the process, degenerate the very part of the brain which allows Humans to experience it. They then go on to say that those Humans who had previously experienced the phenomenon, later took to drugs or committed suicide, as the disparity between this experience and their day-to-day experiences were too great.
The Protagonist aware of the potential consequences undergoes the procedure and experiences the phenomenon, after which, and in conclusion of the story, he notes his newfound state of depression.
