Why do humans (even as infants) dance to music or at least move to its beat?(r/askscience)
This book has a whole chapter on it where they did a study involving babies bouncing to the beat of music…
To summarize, there are theories about babies learning speech patterns (or rhythm) in the last trimester of pregnancy. In addition, the same part of the brain that interprets language interprets music, and can stimulate the areas of the brain for movement (like dancing). It is further theorized that music can cause hormones to be released that generate action in us as humans (such as war chants or heavy metal exciting us and stimulating an adrenaline response). The book goes on to explain how music could be an older form of communication that evolved in our ancestry before spoken language, and that’s why it’s engrained into us before even birth, and why babies bounce to the beat. The specific study I referenced used French babies and German babies to be played a beat that could be interpreted as either a march or a waltz. All the French babies bounced like it was a waltz, and all the German babies bounced like it was a march, which corresponds to the pattern of dissonance and consonance in each of their respective languages.
