The lefreQue Sound Bridge is a simple yet ingenious device that fixes the biggest design flaw in all modern wind instruments: the connections between instrument subsections - that is, the joins between head joint, body, and foot joint - disrupt the smooth production of sound. This is thanks to the break in the material of the instrumental tube. The lefreQue Sound Bridge does exactly as its names suggests and bridges that break.

How It Works: Two precisely shaped pieces of metal (brass, silver, or gold) sit on top of each other to create a miniature acoustic chamber. This chamber is bound with elastic to the flute so that each side of the lefreQue touches a different section - one side touches, say, the head joint, while the other side touches the body. The lefreQue transfers and amplifies the vibrations within the head joint material over the break and into the metal of the flute body. This, then, fully optimizes your instrument for the best tone.

An ever-increasing number of top class professionals fully endorses the benefits of LefreQue sound bridges. Among them Emmanuel Pahud (flute), Steven Mead (euphonium), Bryan Lynch (trumpet), Melton Tuba Quartet (tuba), Kim Laskovski (bassoon), Rupert Gratz (tuba), Evan Tate (saxophone) and many more.

Originally designed for saxophone by Hans Kuijt (an attempt to counteract the non-vibrating cork in saxophone connections), the lefreQue bridges the piccolo's cork connection similarly. The various Sound Bridge sizes (33 millimeter, 41mm, and 76mm) make it easy to optimize the piccolo, flute, alto, or bass for the best sound production, and the variety of metals available allow you to find the best fit for your own instrument.

A special double reed size is also available.

Choosing the Correct Size of LefreQue Plates and Band

Each instrument can use different sizes of lefreQue at different joints. Detailed size charts for each instrument can be downloaded below.
