Black Sabbath is a band, kind of like how Mickey Mouse is a character from Disney. But instead of cartoons, Black Sabbath is all about music. They have lots of songs that some people might think are a little scary or dark, but lots and lots of people love their music.
The band started a long time ago, in the late 60s, when four friends who loved making music decided to start a band together. They were called Black Sabbath because they thought it sounded cool and kind of like a scary movie. The four friends were Ozzy Osbourne, Tony Iommi, Geezer Butler, and Bill Ward.
When they started playing shows, people loved the sound they made. They used loud guitars, thumping drums, and Ozzy's powerful voice to create music that was really different from what anyone else was doing. People started calling it heavy metal, and before long, Black Sabbath was one of the biggest bands in the world.
Over the years, the band members changed a little - some people left and some new people joined - but the music never stopped. Black Sabbath kept putting out albums and playing shows, and even today, lots of people still love their music.
So, to sum it up, Black Sabbath is a band that makes music that some people think is a little spooky but lots of people really enjoy. They started a long time ago and have been making music ever since.
