The video shows a close-up of a guitar's headstock, which is the part of the guitar where the strings are attached. The headstock is made of wood and has six tuning pegs, which are used to adjust the pitch of the strings. The person in the video is using their fingers to turn the tuning pegs, presumably to tune the guitar. The video is shot from a side angle, and the person's hand is visible as they make adjustments to the tuning pegs.
