Viola bows aren’t all created equal. Exotic woods, carbon fiber, graphite composites, and fiberglass are among the materials used to make the bows. Some are designed for professional musicians, while others cater to the needs of intermediate and beginning musicians. Most viola bows are 2.5 ounces (70.87 g) in weight and have 175 tightly strung horse hairs. When shopping for a viola bow, it’s usually best to do some research and comparison shopping because prices vary greatly between retailers and manufacturers.
The difference in viola bows is determined by two primary factors. The bow’s sturdiness is the first. Because the viola is a medium-sized instrument, it necessitates more string pressure than lighter, smaller instruments such as the violin. Beginners are frequently advised by luthiers and viola teachers to begin with a fiberglass bow, which is relatively inexpensive and can withstand the mistakes and inadvertent abuse of the novice player.
Viola bows made of pernambuco wood are commonly used by advanced and professional players. Pernambuco is prized for its tonal qualities and response, but due to years of overharvesting, this Brazilian wood has become increasingly scarce. These bows are typically very expensive, but they are known for having a very long lifespan. Pernambuco viola bows are said to have the kind of spring and smooth action that only advanced players can appreciate.
The length of viola bows is the second factor that distinguishes them. When choosing a bow, the musician’s physical size is taken into account, resulting in nearly infinite length variations. To provide a bow that allows for the most accurate playing, measurements are typically taken between the neck, palm, and wrist. This is especially important for beginners or novice players, because a poorly fitted bow can cause frustration and cause the young musician to avoid practicing.
Viola bows come in two different shapes: octagonal and round. The shape of the bow has little effect on string response, and the musician’s aesthetic preference will determine which version he or she chooses. Violas do not come in standard sizes, and they are typically purchased based on the player’s age. A child might play a viola that is 12 inches (30.48 cm) long, whereas an adult might play one that is 18 inches (45.72-cm) long. Viola bows are made to fit the size of the instrument in either case.
