Super SensitiveRed Label Series Viola D String 15 to 16-1/2 in., Medium
Independent shopping perspective
The Korena take
For 15-to-16½-inch violas, this Red Label Series D string uses a solid steel core with nickel winding and comes in medium gauge. It was developed with student players in mind and is described as responsive, with a bright and powerful tonal character. Its resistance to temperature and humidity changes supports stable use when the viola travels between lessons, school programs, and practice at home. The D string uses a removable ball end; confirm the instrument size before fitting it.
