what is the difference between a violin and a viola?
 The viola is larger than the violin.Violas are wider than the violin.The frog on a viola bow is rounded while the violin bow is pointed. The cello bow also has a rounded frog, but is shorter than both violin and viola bows and weighs around 10 grams more than a viola bow.A standard violin has a body that is 35.5cm long. However, violin bows are around 1 cm longer than viola bows.Generally, because of its thicker strings the viola speaks slower than the violin. That is, it actually takes a bit longer to hear its sound from the time the bow touches the string.
