The wire that wraps around the solid core exists in one of three varieties
Roundwound: This variety utilizes a round wire to create a textured-surface string, as depicted in the diagram.
Halfround: This is a hybrid of the previous two. Through techniques such as mechanical grinding (groundwound) or roller compression (rollerwound), the round wire is partially flattened but not entirely.
Flatwound: It employs a flat wire to form a smooth-surface string.
Among the three, roundwounds are by far the most popular. They are also the most economical option, with the widest selection available. Flatwounds are the second most popular but typically more expensive. Halfrounds are the least popular, and they can essentially be disregarded when shopping for strings.
Now, let us examine how roundwounds and flatwounds compare in terms of performance.
