The violin is a stringed instrument with four strings, which generates vibrations through friction between the strings and bow, and then transmits the vibrations to the backboard through the soundbars inside the resonant box (body). The resonance generated by these parts produces harmonious and bright notes. The violin is widely spread in various countries around the world and is the most important instrument in modern orchestral groups. It plays a very important role in instrumental music, serving as the backbone of modern symphony orchestras and a solo instrument with high difficulty performance skills. Along with the piano and classical guitar, it is known as one of the three major instruments in the world.
