The violin is a string instrument that is played with a bow. It is the smallest and highest-pitched instrument in the violin family, which also includes the viola, cello, and double bass. The violin has four strings, which are usually tuned to G, D, A, and E. The strings are made of gut or synthetic materials, and the bow is made of horsehair.
The violin is held between the left shoulder and chin, and the player uses the left hand to press the strings against the fingerboard to change the pitch. The right hand holds the bow and uses it to draw across the strings to produce sound. The violin can also be played by plucking the strings with the fingers (pizzicato).
The violin is a very versatile instrument and can be used to play a wide variety of music. It is a popular instrument in classical music, but it is also used in many other genres, such as jazz, folk, and rock. The violin is also a popular instrument for solo performance.
