Singing is the act of producing musical sounds with the voice. It often involves using different pitches and rhythms to create melodies. People sing for various reasons, such as expressing emotions, telling stories, or simply having fun. Whether it's a solo performance or a group choir, singing can bring joy to both the singer and the audience. Many cultures around the world have their own unique styles of singing. For example, opera features powerful vocal techniques, while folk music often tells tales of everyday life. Singing can also be a way to connect with others, as seen in karaoke nights or campfire songs.
