Thomastik Peter Infeld Orchestra Double Bass B (H) String 3/4
The Thomastik Peter Infeld Orchestra Double Bass B (H) String is a premium low-register string designed specifically for 3/4 size double basses. It features a flexible spiral rope core with a tungsten and chrome winding, engineered to provide clarity, projection, and a centred tonal core in orchestral environments.

Overview
The Thomastik Peter Infeld Orchestra Double Bass B (H) string is designed for orchestral players who require a dependable and articulate low register. As part of the Peter Infeld series, it is constructed to meet the demands of ensemble playing where a firm, confident low extension is necessary to support a full section. The string is sized for standard 3/4 double basses and focuses on delivering a balanced performance between physical flexibility and tonal rigidity.
Construction and Materials
The internal architecture of the string utilises a spiral rope core. This design choice is intended to offer a more flexible response under the bow compared to solid core alternatives, allowing for easier initiation of notes. The exterior is wound with a combination of tungsten and chrome. The tungsten contributes significant mass and weight to the string, which aids in articulation and helps the low B pitch speak clearly without the 'muddiness' often associated with thick, low-frequency strings.

Tonal Character and Performance
This string is defined by a centred tonal core, which ensures that the pitch remains distinct even at high volumes within an orchestra. It provides high levels of projection and clarity, making it easier for the player to maintain definition in the lowest register. With a tension rating of 30.7 kg, the string strikes a calculated balance; it is firm enough to provide control and resist 'rolling' under the fingers, yet it avoids the overly rigid feel that can hinder a player's nuance and vibrato.
Intended Application
The Peter Infeld Orchestra B string is primarily suited to professional and advanced student bassists working in orchestral or large ensemble settings. Its specific design benefits those who need their low H (B) to sit securely within a section's sound while still being heard clearly by the player and the conductor. While it is an orchestral-focused string, its clarity makes it a versatile choice for any 3/4 bass player needing a reliable low extension.
Market Context
Thomastik-Infeld competes in a market with other specialized string manufacturers such as Larsen and D'Addario. While products like the D'Addario Helicore or Zyex series offer different tonal profiles for various sizes, the Peter Infeld B string occupies a premium space focusing on the specific weight and articulation requirements of the double bass low register. It is priced at approximately £134 for the single string, reflecting its professional-grade materials and construction.
