Thomastik Infeld RONDO Cello Strings

CLEAR AND VELVETY
The THOMASTIK INFELD RONDO® product line is defined by a very clear, powerful and direct sound with a velvety tone color. Cello strings are often associated with the throaty singing of a tenor. However, RONDO® strings sound closer to the chesty voice of a baritone, giving the cello a full, rich and deeper sound. These sound characteristics are also what set the strings apart from other, well-known strings and alternatives within the current Thomastik-Infeld range.
SMOOTH TRANSITION
The RO400 set is very homogeneous. The strings are matched to each other in such a way that the tonal and haptic transition between the strings is almost imperceptible.
THE PRESENT D-STRING
Cellists often complain that the sound and volume of D-strings deteriorate over time. This has been taken into account in the development of this set and the RONDO® D string has been deliberately made to give a present sound. This makes it a stable bridge between the G and A strings! The whole set is very powerful and the sound of the strings fills the room even with little bow pressure.
PLAY AUTOMATICALLY!
The strings respond smoothly and without resistance to every change in playing. All Thomastik-Infeld RONDO® strings offer a playing feel comparable to that of an automatic transmission, creating a comfortable and balanced feel across all four strings in all registers and positions.
FAST RESPONSE    
RONDO® strings have a fast and precise response that is not aggressive.
WHAT ARE AUTOMATIC STRINGS?
When you're on stage, you face many challenges: temperature, humidity, acoustics, your own (nervous) tension. This volatile interplay can make it difficult to fully control movement and sound. Thomastik-Infeld automatic strings provide the perfect support - they are less sensitive to changes in the contact point between string and bow. This allows these strings to compensate for any loss of quality (e.g. response, density, beauty of tone) and respond predictably and reliably. They provide a comfortable and balanced feel, comparable to the automatic transmission of a car.
