The lefreQue is a sound bridge that will make all wind instruments sound better. It consists of a bridge that is built up by two metal elements that will repair the sound breaches that occur in by different parts of a wind instrument. You can put the lefreQue on an instrument using a especially developed elastic band, you do not need to change anything on the instrument itself.
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.
