what is a viola instrument

A viola is a string instrument that is similar to a violin but slightly larger and has a lower and deeper sound. It is the middle or alto voice of the violin family, between the violin and the cello. The viola is typically tuned to C3, G3, D4, and A4. It is played by tucking the instrument under the chin and using a bow or the fingers to sound the strings. The viola has its own distinct qualities and serves an essential function in orchestral music. Its tone is thicker and darker than the violin, making it perfect for providing resonant solo passages in the middle of the orchestral range and blending particularly well with the clarinet and bassoon. A person who plays the viola is called a violist or a viola player.
