Music is an expression of the self, perhaps in its most primeval form. We can talk before we can write, or paint. Human beings, as well as other animals, have used their voice to communicate, and not just by speaking. They elicit cries of war, joy, etc and these are the earliest music forms known to us.
Since then, humans have looked to find new ways of producing music. The first known musical instruments were shells of fruits, rocks. We have now graduated to electric guitars, electronic drums, grand pianos, and many more hugely advanced instruments, but the essence of music is still the same. We'll continue to express ourselves, the way we know best.
