The viola is about one seventh larger than the violin and tuned a fifth lower. It is the only original member of the violin family to exist continuously in the same size. Its tone is deeper and less brilliant than that of the violin. In the 17th and early 18th cent. it was used mainly as an accompanying instrument in the orchestra, but the classical period made it much more independent. It is used mainly in the orchestra and chamber music, but recently has become increasingly popular as a solo instrument.
