In scientific articles, I only found descriptions that were either vague or subjective , as in "postoperative relaxing music" , "slow music" and "group singing" that were shown to lead to higher levels of that chemical.

Can the subjective attribute "relaxing", for example, be translated into an objective formula comprised of parameters that ordinarily describe the properties of sound (amplitude, frequency, sound pressure etc) ?

Has this ever been done ?

Intuitively I would think of genres like Dream Pop or Trance ... or whatever Enya is.

Because the qualia that follows from exposure to these types of music is a kind of jacuzzi - feeling..

But again I would like to justify this subjectively motivated choice for “ best song to boost oxytocin” by describing the sound properties in a less subjective, more observable way. That is, describing the most dominant properties in those songs and subsequently linking those properties- plausibly - to oxytocin release.. So that no eye brows are raised when I explain it.

And so that I can finally choose a song that is , relative to the rest of the music universe, maximally likely to evoke this type of response ( with loads of specificity if possible)

Then I would end up with an experimental means to achieve oxytocin release. I cannot measure the latter directly, so I must make sure that I can explain that this song/piece is more or less reliably going to lead to this physiological response, as opposed to other songs.

Too Long Didn’t Read : I want to find a way to make plausible the link between certain conventional songs and oxytocin release? Ie. describe a song in objective terms and parameters, so as to justify with these parameters in a less subjective way than “This feels really oxytocin-y to me “ my assumption that it will, more so than other songs, lead to oxytocin release in most people?
