About Peter Infeld
Premium construction, expressive range.
Thomastik-Infeld Peter Infeld (PI) strings are premium synthetic-core strings designed for professional solo and chamber players who need exceptional tonal complexity and responsiveness. The PI range offers a rich, complex tone with excellent balance between brilliance and warmth, giving a wide range of dynamics and expressive colour.
The strings are favoured in solo and chamber music settings where expressiveness and projection are essential, and where the player needs a palette broad enough to navigate from intimate pianissimo through to full orchestral projection.

Thomastik-Infeld Peter Infeld viola strings, in short.
What makes Peter Infeld strings different from Vision?
Peter Infeld is the premium tier, designed for soloists and advanced chamber players who need the highest level of tonal complexity, expressiveness, and responsiveness. Vision is the more accessible option, designed for modern players who need a bright, focused sound with reliable performance.
How long do Peter Infeld strings last?
Under regular playing the tone stays consistent for several months. Replace when the sound becomes dull or intonation starts to go false. Wipe rosin off after each session to extend lifespan.
Are these strings authentic Thomastik-Infeld?
Yes. Symphonia stocks Thomastik-Infeld strings through the official supply chain. If a string is faulty on arrival or fails prematurely under normal use, contact us and we will arrange a remedy.
