Changes-Black Sabbath(Cover)

"Changes" is a ballad by Black Sabbath. It first appeared on Vol. 4, which was released in 1972.
The song's piano melody was composed by guitarist Tony Iommi, who was experimenting with the instrument in the studio.[2] The lyrics were by bassist Geezer Butler,[2] and vocalist Ozzy Osbourne has referred to the song as "heartbreaking". Quite different from Sabbath's previous work, the song was described as a "forlornly pretty" ballad by critic Barney Hoskyns.[3] It was inspired mainly by drummer Bill Ward's breakup with his first wife.[2]
