Music originated in prehistoric times when men discovered they could make noises by blowing into wood or hitting objects. It is defined as an art that expresses ideas and emotions through elements like rhythm, melody, harmony, and color. There are many genres of music like hip hop, country, rock, pop, and R&B. Lyrics in songs are important for artists to express feelings and experiences. Studies have shown music can act like a drug for many people who cannot go a day without listening, as it releases similar chemicals in the brain to drugs.
