It's a curious question. Here we have music, which produces sound waves, which gets received in our ears and through vibrations on the skin. Specific frequencies of that sound wave can cause dopamine. But other frequencies don't. Why the difference? Could it be related to memory, having experienced a happy time in your childhood that music brings you back to. What about sad memories? Could it be related to the memories of movies where you had a strong empathy to the emotion of a story and the music was the soundtrack? And what about music you've never heard before. Is there a mathematical rhythm that creates a pattern in the brain that releases dopamine? This is how I think of the question. I am not experienced in any of these subjects to really know the answer.
