Bass guitar strings come in flat wound and round wound. Flat wound bass guitar strings are easier to play and have a mellower sound. I would recommend the flat wound bass guitar strings to someone learning to play the bass. Bass guitar strings also come in different gauges – light, medium, and heavy. You need to know what scale bass guitar you have because the bass guitar strings are sold in different lengths as well. There are short scale bass guitars and extra long scale bass guitars. These different bass guitar strings are not interchangeable. Have fun playing your bass guitar.
