The acoustic violin is a string instrument that produces sound through the vibration of its strings, which are typically made of gut, steel, or synthetic materials. It has a hollow wooden body that amplifies the sound, allowing it to be heard without electronic amplification. The violin is played with a bow, which is drawn across the strings, or by plucking the strings with the fingers. The instrument has four strings tuned in perfect fifths, and it is known for its expressive range and versatility. The acoustic violin is a key component in various music genres, including classical, folk, and jazz, and is often featured in orchestras and chamber music ensembles.
