What is a lefreQue

Sound bridge for wind instrument

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 different parts of a  wind instrument. You can put the lefreQue on your instrument using an especially developed elastic band. You do not need to change anything on the instrument itself.

Saxophone- and flute player Hans Kuijt at first invented the lefreQue for the saxophone, being unsatisfied with the sound quality of even the very best instruments. He concluded that all connections between the different parts of a wind instrument have a negative influence on the sound quality and tuning. Cork is a material that absorbs sound. You can use it perfectly to fit a mouth piece airtight to the instrument but at the same time, the properties of cork are such that it obstructs proper transmission of the required sound from the mouthpiece to the instrument. It actually mutes sound. LefreQue solves these problems.

For all wind instruments

Finding that the invention worked perfectly on all types of saxophone, Hans was curious to find out what the lefreQue would do on his flutes. On the flute there are no cork connections, but the lefreQue does the job essentially in the same way. Clamped connections at the joints of all wind instruments introduce  frequency dependant resistances (sound breaches), which can be corrected by using the lefreQue sound bridge.
