Musicality. What is music?

"...You're listening to your first song. The consistent rhythm is the beat of your mother's heart. The uterine blood and amniotic fluid flowing around you create that gentle drone. Consonants and high frequency sounds are filtered by the layers of skin and fat in your mother's abdomen, but you can hear a soft melody of low frequency bass and vowels. Your eyelids are closed until 28 weeks after conception, but you start to hear at week 18. Before even knowing there's a world to see, you're immersed in a world of music.
...
Not only does musicality ... predate the alphabet song, musicality predates the alphabet itself. And all written language - by a lot...Before our ancestors developed writing, values, memories, and customs were conveyed through song. Ethnomusicologist, John Blacking, suggests singing and dancing preceeded Homo Sapiens by several hundred thousand years. Caves are full of accoustic reverberations - like your shower. That must have made cavemen 'ugh' feel like Pavarotti..."

The VSauce series of videos must produce some of the best informational, educational and entertaining video essays on YouTube. This is Kevin Lieber's (aka VSauce2's) video essay on musicality. As usual, he provides sources for the data he references in his videos. Approx 14m of watch time:

Near the end of his video essay, he tells the heart-breaking story of Clive Wearing, musician and ex-BBC music director. Clive Wearing's only reprieve from the symptoms of both Retrograde Amnesia (unable to recall the past) and Anterograde Amnesia (30-second, short-term memory) is when he is playing the piano.

"...After every handful of blinks, Clive's eyes open to a brand new world. His subsequent loneliness, confusion and constant fear left him feeling robbed of consciousness. He says it's like being dead..."

(I'll post the video documentaries on Clive Wearing's life in a separate post.)
