Pirastro Obligato cello strings represent a pinnacle of modern synthetic string innovation, blending the rich, complex warmth and overtones of traditional gut strings with the stability and responsiveness of advanced materials.

Crafted with a cutting-edge multifilament synthetic core for the D, G, and C strings—wound in chrome steel and tungsten—and a steel-core A string for brilliant projection, Obligato delivers a powerful, brilliant sound that is big, focused, and full of color.

Cellists praise its exceptionally quick response, excellent playability across the dynamic range, and remarkable projection, making it ideal for warming up brighter instruments while surpassing many gut alternatives in clarity and power.

Completely insensitive to temperature and humidity changes, these strings offer reliable performance in any environment, with a relatively short break-in period that reveals a warm yet vibrant tone.

Perfect for advanced and professional players seeking depth, brilliance, and versatility—whether in solo, chamber, or orchestral settings—Obligato strings elevate the cello's voice to expressive new heights.
