Instruction: What is an string instrument that is similar to a Violin, but larger in size and with a lower and deeper sound?

Context: The viola (/viˈoʊlə/ vee-OH-lə, also UK: /vaɪˈoʊlə/ vy-OH-lə, Italian: [ˈvjɔːla, viˈɔːla]) 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.

Response: The instrument you are looking for is a Viola.
