"Yes," Artemis confirmed. "There's a metal core, and then thin metal strips are wrapped tightly around the core. The string is then stretched between holes down here," he circled the area. "And pegs up here to obtain a certain tone or note. The process is more art than science, especially with stringed instruments. Obtaining a pleasing tone is very difficult at first. You have to develop recognition for tones.

"Musicians can alter the tones of these strings by placing their fingers in certain spots and vibrating the string by plucking it or running the bow over the string. Combinations of these tones create music.

"At least, that is how it works in my world," Artemis finished, a little unnerved that Haku would be bored to tears.
