Rondo Cello String Set

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 in such a way that the tonal and haptic transition between the strings is hardly noticeable. 

THE PRESENT D-STRING
Cellists frequently complain that the sound and volume of D-strings deteriorates after a short time. This was taken into account in the development of this set, and the RONDO^® D-string was deliberately manufactured to emanate a present sound. This makes it a stable bridge between the G- and A-string! The entire set is very powerful and the strings’ sound fills the room even when little bowing pressure is applied.

PLAY AUTOMATIC!
The strings respond smoothly and without resistance to every change in playing. All Thomastik-Infeld RONDO^® strings offer a playing feel comparable to a driving experience with automatic transmission: they create a comfortable and balancing 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?
You’re faced with many challenges on the podium: temperature, humidity, acoustics, your own (nervous) tension. This volatile interplay can make it difficult to completely control movement and sound. Thomastik-Infeld automatic strings provide the perfect support here – they are less sensitive to changes in the contact point between string and bow. This allows these strings to compensate for any possible losses in quality (e.g.: response, sound density, tone beauty) and react predictably and reliably. They provide a comfortable and balancing feeling, comparable to the automatic transmission of a car. 

The RONDO Experience®
The Thomastik-Infeld RONDO Experience^® RO41XP is a very vibrant string and offers an exceptional amount of sparkle and overtone richness compared to the regular RO41. It reacts even faster to bowing impulses from the right hand and at the same time produces a clear, distinct sound with minimum effort from the left hand.

The string has 700g less string tension, but it is exceptionally powerful and creates a very compact sound despite a broad range of tonal colors, unlike other softer strings. However, unlike the standard RO41, the sound density of the RO41XP is lower. Even though it feels softer (than the RO41), it offers a nice resistance. Compared to the RO41, the RO41XP is more sensitive to bow pressure and bowing speed, offering a higher capacity for modulation. Due to its forgiving character, the RO41XP maintains contact close to the bridge very reliably even when the bow pressure is insufficient.

Due to its even faster response (see RO41), the Thomastik-Infeld RONDO Experience^® RO41XP allows impulsive interpretations and new playing experiences as a result.
