What is music?
Suppose you hit a wooden table with your hand. It makes a sound. Now suppose you hit a ball. It makes a sound. The second sound is called a tone. A tone is a single musical sound. Music is the art of organizing tones into meaningful patterns of sound. We might call it the language of tones. Sometimes the language of music speaks to us in tones sounding after one another in melody. Or the tones could be sounding together in harmony.
