This is an interesting read. It’s always easy for a hard scientific study to discard or consider cultural elements. They are so much more difficult to quantify. But considering that music is so deeply embedded in the culture from which it emerges, it seems folly to not have it as a consideration. When dealing with music, it is hard to separate intervals from meaning. Begs the question that if music is a language, why is every dialect different? Music is much more complex than that, in my opinion.
