Viola
The viola is one of the four main String Instruments that comprise a string orchestra. It serves as the alto voice of the violin family.
Though similar in shape to a violin, the viola is slightly less smaller and lower in pitch by five notes. The tone of the viola also sets it apart from the violin, being more richer in tone and sound.
The viola is subject to many jokes because of its lesser role in orchestral music, implying that one does not require as much talent to play it. However, many musicians claim that the viola is actually more difficult to play and it rewards more than the violin.
Some famous viola players include William Primrose, Paul Hindemith, Yuri Bashmet, Nobuko Imay, John Cale, and Whit Schroder. Many famous violinists also play the viola as a secondary instrument, such as Itzhak Perelman and David Gilmour.
