Gravi-kora is a cool instrument that combines two things: gravity and a musical instrument called a kora. So, let's break it down step by step!
First, let's talk about gravity. You know when you drop a toy from your hand, it falls down to the ground? That's because of gravity! Gravity is a special force that pulls things towards each other. It's what keeps us grounded on the Earth and makes things fall when you let go of them.
Now, let's talk about the kora. The kora is a really interesting musical instrument from West Africa. It looks like a big wooden harp with strings. To play it, you pluck or strum the strings with your fingers and make beautiful sounds.
Now, imagine combining gravity and the kora! That's what the gravi-kora does. It has the shape and strings of a regular kora, but it has a special feature. It has metal balls attached to each string. These metal balls can move up and down the strings because of gravity!
When you pluck or strum a string on the gravi-kora, the sound you hear is made by the vibrating string. The metal balls on the string move up and down too as the string vibrates. This creates a really unique sound, different from a regular kora.
The gravi-kora allows the musician to create interesting melodies and rhythms by changing the way they play the strings. They can make the metal balls move faster or slower, creating different sounds and musical effects. It's like playing a normal kora, but with an extra touch of gravity!
So, in simple words, the gravi-kora is a special instrument that uses gravity to make really cool sounds. It has strings with metal balls that move because of gravity when you play it. It's a fun and creative way to make music!
