Why buy as a set
Three reasons to take the whole pack.
Tonal coherence
All four strings share the same Obligato voicing and construction. The warm, even balance across the instrument is designed as one matched set.
Better price per string
The complete set is $20 less than buying the four strings individually at the same Pirastro quality.
Consistent settle-in
Replacing all four at once means the set breaks in uniformly. Mixing old and new strings can leave the instrument tonally unbalanced while the new string settles.
About Pirastro Obligato
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 associated with gut strings, without the tuning instability. The set stays consistent in changing humidity and temperature, making it a dependable choice for orchestral schedules, touring, and pit work.
Obligato responds quickly under the bow, feels soft under the fingers, and settles promptly. Made in Germany by Pirastro. SKU 83910.
The four voices
What each string brings.
A · Synthetic / Aluminium
Lyrical treble
Synthetic multifilament core with aluminium winding. Focused and lyrical, never brittle. Warm character without sacrificing clarity in high positions.
D · Synthetic / Aluminium
Velvety midrange
Matched synthetic core with aluminium winding. Velvety and elegant, blending naturally in ensemble and projecting cleanly in solo playing.
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.
Playability
Soft under the fingers, consistent in any room.
Obligato feels soft under the left hand, reducing fatigue across long rehearsals. The strings respond readily at lower bow pressures and speak clearly across the full dynamic range. The synthetic core keeps the set stable across changes in humidity and temperature.
The set settles promptly after installation and maintains consistent tuning throughout. Particularly effective for instruments that sound too bright on steel-core sets, or for players seeking a richer, more complex palette from their cello.

Frequently asked
Obligato set, in short.
What is included in the set?
The set includes all four strings: A, D, G, and C in Pirastro Obligato Medium. SKU 83910, each string in Pirastro packaging. Ball ends, fine-tuner ready.
Why is the set cheaper than buying the strings separately?
Pirastro prices the set to encourage complete replacements. Replacing all four at once ensures tonal coherence and consistent break-in across the instrument.
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 loses its warmth or becomes dull.
How long do new strings take to settle in?
Allow 24 to 72 hours of normal playing. The synthetic core settles more quickly than gut and is stable across temperature and humidity changes. Retune gently and wipe rosin 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.
