A musical whistle, essentially characterized by the fact that it is made up of the union of three pieces of metal of adequate size and shape to adapt to the mouth and lower part of the nose, which form underneath a small curved duct that carries the air or breath from from the nose to a rectangular opening in correspondence with the mouth, provided with small vertical partitions posterior and lateral and that is regulated by the movement of forward or backward movement of the tongue on the palate, varying with this movement the passage of the nasal air through the conduit, which allows to emit the sound more or less high, as desired, constituting a musical whistle.
