The first thing you need to look for when buying your bass guitar is the number of strings it has. A bass guitar can come with four, five, or six strings. The four string bass is the one that you may see most often and it is the easiest one for beginners to learn. The five or six string bass is for players who like to play around with different musical styles or perform a lot of solos. For a beginning bass player, I would recommend that you may start with the four string bass.
