Thomastik Peter Infield 3/4 Set - Medium

Designed to Meet the Demands of Orchestral Playing

Peter Infeld strings are designed for double bassists seeking a balance of presence, harmonic richness and stability. Their construction is based on a proven spiral core, combined with a carefully developed selection of materials to provide an even response across the entire range.

This set in orchestral tuning offers substantial overall tension, making it ideal for achieving clear projection without sacrificing depth in the low register. It is particularly well suited to 3/4 instruments used in orchestras, classical ensembles or settings requiring precise articulation.

Strings for Advanced and Demanding Double Bassists

These double bass strings are intended for advanced intermediate, experienced and professional musicians looking for a responsive and reliable set. Their tension and tonal character encourage committed bowing, with a clear attack and precise control over dynamics.

They are a natural fit for classical, symphonic and chamber music repertoire. Their definition in the midrange also helps maintain a clear bass line in acoustic jazz groups and contemporary ensembles, provided a firm, structured response under the fingers is desired.

The Sound

The Peter Infeld set stands out for its focused, full and expressive tone. The midrange benefits from a strong presence, helping bring out attacks and preserve the clarity of phrases within a double bass section. The low register retains density and support, while sustained notes maintain excellent stability.

The spiral core contributes to efficient vibration transmission to the top, bridge and body of the double bass. The chrome steel winding provides an even response and a feeling of control under the bow. The result is a richly coloured tone that can remain powerful without becoming aggressive.

The G string enhances clarity and precision in the upper register. The D and A strings provide a smooth transition through the heart of the range, with a solid midrange. The E string delivers a generous, stable and well-defined low-end foundation, essential for supporting the instrument as a whole.
