Hey! We are really really sorry for this late reply!! So busy over here right now...
The Schumann-Frequency is the "frequency of the earth". It´s resonances of the earth´s magnetic field. It´s around 7.83Hz. So it does make total sense that this effects our bodies and souls.
Underwater speakers and experimenting with these frequencies sounds VERY interesting!! Is he on Hive?
Well there are different methods on how to set the frequencies to the music.
You could either try and compose the music in a key that fits to the frequencies, which is rather hard to do most of the times.
But there are different techniques, such as Binaural Beats, Monaural Beats, Subliminals or Isochronic Tones. Each of these need to be composed and produced different. If you wanna know more about one specific way, we can tell you more about it. :)
