Scaled to fit 4/4 scale violin with a playing length of 13 inches (328mm), these heavy tension strings will allow for greater projection and volume potential. Packaging in uniquely-designed sealed pouches provides unparalleled protection from the elements that cause corrosion. Kaplan violin strings offer professional-level players an unprecedented combination of beauty and power in two options, Kaplan Vivo and Kaplan Amo. Kaplan Vivo delivers brilliance, clarity, and a robust feel for darker instruments, while Kaplan Amo provides warmth, richness, and flexibility for brighter instruments. Both sets settle quickly, exhibiting a rich tonal color palette and superb bow response.
