rehairer

A rehairer is a craftsperson who specializes in replacing the hair on stringed instruments, most commonly bows for violins, violas, cellos, and double basses. This process, known as rehairing, is essential for maintaining the playability and sound quality of these instruments. Bow hair, typically made from horsehair, wears down over time with use, becoming smooth and losing its grip on the strings. Without adequate grip, the bow will produce a weak or inconsistent sound and can become difficult to control.

The rehairing process involves several distinct steps. First, the old hair is carefully removed from the bow stick. This often involves heating a wedge that holds the hair in place, allowing it to be loosened and extracted. Once the old hair is gone, the rehairer selects new horsehair of appropriate quality and length. The new hair is then bundled, measured, and inserted into the frog of the bow. The frog is the part of the bow that the player holds. The rehairer then tightens the hair by advancing the button, a mechanism that extends the frog away from the tip of the bow. Finally, the hair is cut to the correct length and secured at the tip, often with a wedge. The tension of the hair is then adjusted to the player's preference.

Skilled rehairers possess a deep understanding of the materials and techniques involved. The quality of the horsehair, the precision of the insertion, and the proper tension all significantly impact the bow's performance. Rehairing is a specialized skill that requires patience, dexterity, and a keen ear for sound. Many professional musicians rely on experienced rehairers to maintain their instruments and ensure optimal playing conditions.
