Specifications of Tailpieces

Using our Sonowood material and the wood composite Ebonprex, we manufacture tailpieces in various shapes, lengths, materials and designs.

Models
Dimensions

We manufacture the Classic, Tulip, Lily, English, and Baroque models in various lengths. The length of the tailpiece should be selected based on the vibrating string length (in mm) and the distance from the rear edge of the bridge to the tip of the nut (in mm). The free-swinging string behind the bridge should be at least 1/6 of the vibrating string length.

Lengths for violin

100 mm, 106 mm, 109 mm, 112 mm

Lengths for viola

120 mm, 124 mm, 128 mm, 132 mm, 136 mm

Lengths for cello

215 mm, 225 mm, 235 mm, 245 mm
