Viola [SEP] Introduction
The viola ( , , ) is a string instrument that is bowed, plucked, or played with varying techniques. It is slightly larger than a violin and has a lower and deeper sound. Since the 18th century, it has been the middle or alto voice of the violin family, between the violin (which is tuned a perfect fifth above) and the cello (which is tuned an octave below). The strings from low to high are typically tuned to C, G, D, and A. In the past, the viola varied in size and style, as did its names. The word viola originates from the Italian language.
