Set details

The RONDO set RO200 is an ideal choice for professional musicians due to its high dynamic range and volume as well as its beautiful warm and sweet sound. These strings are easily playable and have an excellent bow response. A rich sound and compact substance combined with a great balance between broad sound and distinct focus supports musicians in challenging situations. This balance enhances a deep sound in the lower strings and adds warmth and sweetness in the upper ones. The main characteristic of this set is its powerful sound and great projection that enables the musician an almost effortless soloistic, chamber music and orchestra performance. With Rondo it is easy to transmit any musical nuance due to its big range of sound colors and great modulation capacity. The set is highly corrosion resistant and offers a long life-span.

Mix and match

The Rondo viola strings can be combined very well with Peter Infeld strings, especially RO23 and RO24 with PI21 and PI22A.

The combination of PI21 and PI22A with RO23 and RO24 enhances the strings´ full-bodied character and warmth.

The Rondo RO21 and RO22 combine well with Spirocore G and C strings especially with reduced tension (weich) – S20W and S24W. This combination results in an easy sound, a very good bow response in the upper strings and deep sound in the lower ones.
