Louis is hoping to generate enough interest in the instrument to find a sponsor and put the aulochrome into production.

The aulochrome is made from two Borgani saxophone bodies welded together, with a double mouthpiece and other parts constructed by Louis. It took him two years to create it.

According to the Daily News, the instrument produces two sounds, one brighter than the other, making it difficult to place the sound's location.

So far the aulochrome has impressed many of those who have heard it. "It's the sound of the third millennium," Lovano said. "This is the horn everybody will be playing 100 years from now."
