Top Ten Best Number of Members In a Rock Band

1 as vocals, 1 as bass guitar, one as Guitar, 1 as drums( the lead vocalist could also play rhythm guitar, or bass, and if the vocalist plays bass, you have 2 guitarist. 1 lead, 1 Rhythm)

Then if the singer is the bassist, it will be easier for him to be in sync with himself.

4 is perfect! A vocalist, guitar player, base player, and drummer! Great!

I always like bands with 4 members.

One job for every one. Vocalist, drummer, bassist, Lead guitarist, and rhythm guitarist

Vocalist, Guitarist, Bassist, Keyboardist and Drummer

1 lead singer who plays guitar or bass guitar, 1 drummer, and a Bassist or guitarist

Best number for Metalcore bands, a Drummer, a lead guitarist, a rhythm guitarists, a bassist, a keyboardist and a lead or unclean vocalist (if the vocalist dose unclean vocals then one of the other members with do the clean vocals, normally the rhythm guitarist)

A vocalist, guitarist, bassist, drummer, keyboardist, a rhythm guitarist

Vocalist, Keyboardist, Drummer, Lead Guitar, Bass, and rhythm Guitar

Only slipknot has 9 people and that's ridiculous
