a four string instrument commonly tuned to EADG and is similar to the guitar but has a lower pitch. The bass is usually used for rhythm and to give texture to the music. A lot of idiot guitarists say bass is not needed but that is untrue. I'm a guitarist and sometimes I do wish I picked the bass (no pun intended). Some legendary bassists include John Entwhistle, John Paul Jones, Charles Mingus, Roger Waters, and Krist Noveselic.
