<p>A sound filter representing a link between the wind instrument mouthpiece and the entry tube of the wind instrument is solving the problem of sound vibrations of all musical wind instruments in such a way that outer vibrations created at the mouthpiece and running along the exterior side of the wind instrument tube are modified and directed inward towards the centre of the inner tube. In the same time, the sound is cleaned of a metallic tone, the tone vibration is improved and beautified imparting more softness to the sound and filling up all the space within the tone volume. It cleans the tone colour, gives still a greater strength and density to it resulting thus in a higher quality, a more beautiful colour and a purer intonation.</p> |
