The Structure of the Violin
The structure of the strings
The violin has four strings
From high to low, the strings on the violin are E, A, D, and G. They are made from a variety of materials including catgut (sheep intestine), nylon, and steel.
The tuning pegs are used for tuning
The neck is carved from a single piece of wood, and the part at the end that appears to wind in on itself is called the "scroll." The strings are attached to the tuning pegs, which are fitted inside narrowly carved holes, and held in place by friction.
Only the high E string has an adjuster so that it can be easily tuned, while the others rely on the tuning pegs for tuning, which might take some getting used to.
Recently, some violins come with four adjusters built into the tailpiece, so this is another option to consider.
