Thomastik-Infeld describes the Rondo strings as follows:
RONDO FOR VIOLIN
Rondo violin strings work on many different instruments but are particularly popular among soloists playing old instruments. The (standard) set comes with a synthetic core, aluminum wound A-string, providing great modulation and a rich spectrum of sound colors. For those wanting to stay true to the traditional steel A-string or looking for 100% corrosion resistance and easier playability, Rondo offers a steel A-string without the common downsides of sounding too bright or shrill.
- Great balance of warmth and brilliance
- Soloistic power
- Vast dynamic range
- Immediate bow response
- Reduces wolf tone
