Why a lefreQue

From a sound quality perspective, the tube of your wind instrument would ideally consist of one piece. For practical reasons however (tuning, transport, technical constraints), wind instruments - as we use them today - consist of different sections. LefreQue is a revolutionary sound bridge that acoustically connects the sections of your wind instrument, combining the benefits of both.

The result is an unequaled improvement of your sound quality: purer overtones, accurate tuning, clear response, smooth intervals, extended dynamics, surround projection.

Scientific research 

We are pleased to inform you that an independent scientific article with the title  "The Magnitude of the Frequency Jitter of Acoustic Waves Generated by Wind Instruments Is of
Relevance for the Live Performance of Music" has recently been published (June 12th, 2021) in "Acoustics" and is available online. 

Acoustics is a peer-reviewed, open access journal of acoustics science and engineering, published quarterly online by MDPI.  Based in Basel, Switzerland, MDPI has the mission to foster open scientific exchange in all forms, across all disciplines. It's 352 diverse, peer-reviewed, open access journals are supported by more than 84,200 academic editors around the world.
