Thomastik Peter Infield 4/4 A - Medium

A Peter Infeld string designed to combine power and refinement

The Peter Infeld PI41 cello string embodies a high-end approach to tone: delivering strong projection without losing richness of color. It combines a direct, energetic presence with a refined sound that preserves the instrument’s acoustic character.

This A string was developed to meet the expectations of musicians seeking a more expressive setup, capable of remaining clear and stable both in fast passages and in lyrical playing.

For advanced cellists and expressive performances

The Peter Infeld PI41 is primarily intended for advanced intermediate, accomplished and professional cellists. Its quick response effectively supports precise bowing, while giving the player extensive control over attacks, dynamics and register changes.

It is suitable for Classical, Romantic and contemporary repertoire, as well as for performers looking for a responsive A string for chamber music, orchestral playing or solo performance. Its dynamic reserve facilitates generous crescendos as well as carefully shaped pianissimi.

The sound

Thanks to its carbon steel core and Multi Alloy winding, the Peter Infeld PI41 A string delivers a powerful, focused and richly colored sound. The middle register gains density, promoting beautiful continuity between the cello’s registers.

Its tonal character combines projection and finesse: the attack remains lively, the response is immediate and the sound retains an appealing elegance in melodic lines. Its wide dynamic range allows for a full and nuanced performance without sacrificing articulation definition.

Recommended compatible accessories

This cello A string can be fitted to a cello equipped with a traditional tailpiece or a tailpiece with a fine tuner suitable for steel strings. Cello rosin offering good grip can also help make the most of its quick response and power, particularly during energetic bowing.
