The viola (/viˈoʊlə/ vee-OH-lə, also UK: /vaɪˈoʊlə/ vy-OH-lə, Italian:) is a string instrument that is bowed, plucked, or played with varying techniques. Slightly larger than a violin, it 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 C3, G3, D4, and A4.
