Sure, “clear” was an exaggeration, and I don’t want to get into a scientific debate because I’m neither a scientist nor someone who enjoys a debate. But just for the record, there are more papers on this than just that one I linked to (e.g. Bowling). And, to your point, the data isn’t clear, there are lots of theories floating around.
I’m just curious about whether this thing is universal, or whether it’s due to culture, because if it isn’t due to culture, then in theory, we may not be the only species that have these emotional associations, which I find to be a fascinating possibility.
Even a skeptic like Philip Ball seems to agree on some baseline statements, e.g.
So although it’s simplistic to suppose that all music is happy or sad, these crude universal indicators of emotion do seem to work across cultural boundaries.
Neuroscientist Daniel Bowling and colleagues at Duke University in Durham, North Carolina, compared the sound spectra — the profiles of different acoustic frequencies – of speech with those in Western classical music and Finnish folk songs. They found that the spectra in major-key music are close to those in excited speech, while the spectra of minor-key music are more similar to subdued speech1.
This made me reflect on my own experiences with cats, having been a cat owner for at least 30 years of my life. Cats have a tendency to end their meow in an upward pitch in the end when they’re happy, and the other direction when they’re sad or anxious. This at least seems to be a global phenomena because I’m recognizing the same cat speech all around youtube. That’s not music, of course, but it’s harmony and dissonance.
Anyway, I think this is a fascinating topic, but I don’t have the answers, hence this original post.
