Medium, Ball end. These new violin strings combine moderate tension and full sound, without compromising clarity and subtlety. They offer easy playability and fast response to achieve a finely nuanced sound. Larsen's Virtuoso strings are available in two tensions: medium and strong. The medium set has slightly less tension than an average set of medium strings and is most suitable for orchestral and chamber music playing. The strong set is slightly higher tension than a regular medium set and have a stronger, more brilliant sound suitable for solo playing.
