The guitar neck is the long, narrow part of a guitar that extends from the body to the headstock. It is typically made of wood and features a fingerboard, where the player presses down on the strings to create different notes. The neck is essential for playing melodies and chords, as it provides the necessary frets that help define the pitch of each note. At the end of the neck is the headstock, which holds the tuning pegs. These pegs allow the player to adjust the tension of the strings, ensuring the guitar is in tune. The design and length of the neck can vary between different types of guitars, such as acoustic and electric guitars.
