Structural characteristics of the viola instrument
The viola is very similar to the violin but with a different size. The size of this instrument is a little bigger than the violin and it is 5 cm longer, because the difference in size is very small, sometimes it is difficult to separate it from the violin. Also, its sound range is lower than that of the violin, and its playing style is similar to that of the violin. In terms of sound range, this instrument has a sound between violin and cello. The body of the instrument consists of four parts: handle, strings, resonating bowl, and bow. The number of strings is the same as that of a violin, four, and since it is larger than a violin, its strings are also thicker. The resonating bowl is pear-shaped and usually made of hardwood such as ebony or rosewood. The bow is also made of horse hair. Among the most important viola players in the world, we can mention Carl Stamitz, Lionel Tertis, William Primrose, Nobuko Imai, Yuri Best, Lawrence Power, etc.
