The instrument played by using a bow is the violin. The violin is a string instrument with four strings that are typically tuned to perfect fifths. It is played by drawing a bow across the strings, producing sound through the vibration of the strings. Violinists can also use their fingers to press down on the strings to create different pitches. The violin is integral to various music genres, including classical, jazz, folk, and more. Renowned for its expressive range and versatility, the violin is often a key component in orchestras and ensembles.
