Description

The Peter Infeld C String by Thomastik-Infeld is crafted for cellists who demand strength, body, and responsiveness from the lowest register of their instrument. Designed for professional use, this string completes the PI set with tonal power and balance, contributing greatly to the instrument’s foundational voice.

Rich Bass and Focused Depth
Engineered with a tungsten/chrome winding over a spiral core, the C string produces a deep, resonant tone with impressive clarity. It projects easily in solo and orchestral settings without sacrificing warmth, making it especially well-suited for passages requiring weight and precision in the lower end of the cello’s range.

Effortless Control and Projection
The PI C string offers a quick response under the bow while maintaining stability under varying pressures. Its evenness across dynamics gives players the freedom to shape musical phrases with control and nuance. Whether you’re performing Brahms in a concert hall or recording Bach in a studio, this string adapts seamlessly.

Integrated Tonal Blend
When paired with the other strings in the Peter Infeld line, the C string anchors the instrument’s voice with balance and projection. It also blends beautifully with other Thomastik lines like Spirocore tungsten for added punch or Versum for increased warmth—ideal for advanced players customizing their tonal setup.

Durability and Tuning Stability
Its construction is designed for long-lasting performance and stable tuning. This is essential for professionals who rehearse and perform frequently, as the C string resists fatigue and wear, even under demanding conditions.

Recommended For:

  • Cellists seeking low-end power with tonal clarity
  • Soloists needing strong projection in the bass register
  • Chamber musicians and orchestral players
  • Recording artists looking for focused resonance
  • Advanced students and professionals alike
