A musical whistle, essentially characterized by the fact that it is made up of the union of three pieces of adequate size and shape to be adapted to the mouth and lower part of the nose, which form underneath a small curved duct that carries air or breath from the nose towards a rectangular opening in correspondence with the mouth, provided with small vertical posterior and lateral partitions and that is regulated by the 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.
