What is the difference between a group and a band?

A band is a group of people that make music. Usually they have a singer, a drummer, and some Guitars and maybe a keyboardist if needed. Some examples of bands are : 30 Seconds to MarsTokio Hotel Within Temptation NSYNCBreaking Benjamin Evanescence On the other hand, an artist is one person, and they usually are singers. They have other people fill in the music that people in the band would usually do (drums, guitar, keyboard, special sound effects, violins and other intruments) Examples of these would be : Rihanna Leona Lewis Justin Timberlake Madonna So all in all, bands have more than one person, and have lots of intruments and different parts to them, and artists are usually singers and known for themself, not as a group.
