The modern classic for players who want gut-like richness.
Pirastro Obligato is built around a synthetic multifilament core tuned to deliver warm, dark tone and even response across the instrument. The construction gives cellists the richness and tonal complexity associated with gut strings, without the tuning instability that comes with real gut. The set stays consistent in changing humidity and temperature, making it a dependable choice for touring, pit work, and busy orchestral schedules.
Obligato responds quickly under the bow, rewards nuanced contact-point work, and feels soft under the fingers. The strings settle promptly and deliver reliable tuning stability and consistent articulation across varied environments. Made in Germany by Pirastro.
The four voices
What each string brings.
A · Synthetic / Aluminium
Lyrical treble
Synthetic multifilament core with aluminium winding. A singing top that is focused and lyrical, never brittle. Warm character without sacrificing clarity in high positions.
D · Synthetic / Aluminium
Velvety midrange
Matched synthetic core with aluminium winding. A velvety middle register that blends naturally in ensemble playing and carries with elegance in solo contexts.
G · Synthetic / Silver-Based
Round resonance
Synthetic core with silver-based high-density winding. Round and resonant, with a focused, singing core that projects warmly without losing definition.
C · Synthetic / Silver-Based
Noble foundation
Synthetic core with silver-based winding. Dark and noble, with powerful presence and sustain in the low register. A rich foundation for the full instrument.
Playability
Soft under the fingers, consistent in any room.
Obligato strings feel soft under the left hand, which reduces fatigue across long rehearsals and touring schedules. They respond readily at lower bow pressures, reward nuanced contact-point work, and speak clearly across the full dynamic range from pianissimo to fortissimo.
The synthetic core keeps the set stable across changes in humidity and temperature, making Obligato a reliable choice for orchestral players who move between rehearsal spaces, pits, and stages. The set settles promptly after installation and maintains consistent tuning throughout.

Frequently asked
Pirastro Obligato cello strings, in short.
How long do Obligato strings last?
Lifespan depends on playing hours, perspiration, and environment. A daily-playing professional or advanced student should expect several months of consistent tone. Replace when the sound becomes dull, unfocused, or loses its warmth.
How long do new Obligato strings take to settle in?
Allow 24 to 72 hours of normal playing. The synthetic core settles more quickly than gut and is more stable across temperature and humidity changes. Retune gently and wipe rosin residue off after each session.
Are these genuine Pirastro strings?
Yes. Symphonia stocks Pirastro Obligato through the official supply chain. If a string is faulty on arrival or fails prematurely under normal use, we arrange the replacement directly.
How does Obligato compare to gut strings?
Obligato is designed to give cellists the warmth, tonal complexity, and soft feel of gut, but with the tuning stability and environmental consistency of a synthetic core. Players who want gut-like tone without the tuning unpredictability and weather sensitivity of real gut often find Obligato the ideal bridge between the two worlds.
