Every American knows that saying that slaves had it horribly is criminally understated. Horrendously. White people basically banned their culture. I was curious about the musical aspect of that, because I remember learning in one of my high school history classes that slaves used to sing at night. And sing they did.
Singing became a way to express their emotions, lift each other up/console each other, and communicate with one another. Many of the songs were spiritual, but they also had codes -- hidden meanings. Imagine my surprise when I learned that the song "Swing Low Sweet Chariot" was actually a song from the Underground Railroad, sang by African slaves who were getting ready to attempt their escape. There are many other songs of the Underground Railroad, all coded, and you can find a bunch of them online. It's amazing which details get glossed over in history classes.
On a lighter note, I'm obsessed with drums of any kind, so I wanted to do a little bit of research on the history of drums in Africa, since Africa's history is so long. Similarly to Native American culture, drums were considered the heartbeat of tribes and communities. There's a small country in East Africa called Burundi, and one of the things the people there are best known for is the drums; more specifically, a group called the (Royal) Drummers of Burundi. Playing the drums is passed through generations, but they don't just play -- they dance and jump around and sing, as well. They have been touring for quite a while, and are considered one of the greatest percussion groups of all time.
Alright, so I admit it: I was one of the people who heard the country Madagascar and, unsurprisingly, immediately thought of King Julien. I mean, come on, how could you not? He moved-it moved-it right into your heart, just like mine. Don't lie.
Of course, real lemurs (from Madagascar and elsewhere), can't talk, dance, or sing in English -- but actually, there is a species of lemurs native to Madagascar who are considered to be able to "sing." They're called Indri Lemurs, and they sing in groups (usually their families) to scare away other lemurs that might try to encroach their territory, communicate, to prove their strength to other lemurs, and occasionally even used as a mating call (though that isn't the primary reason). When one lemur starts to sing, the rest join in and will sometimes fall into unison in regards to rhythm and pitch.
It's not technically music or singing, but I still thought it was super cool anyhow.
Fair warning: their song sounds like if an airhorn and a toddler yelling were combined.
