Luis generously sent me one of his nose flute. It is a huge nose flute, with carvings, a blue cord and red tassels: a great "country" version of the instrument. The front is ornated with a celtic knot, between a pair of bevels made to block a rubber head cord for handsfree playing.
All the work was done by hand, with simple tools. This explains some irregularities, but totally fits the choice to make a "country" nose flute. The whole is perfectly consistent.
As the front side is angular, the back side is carved with curves and creates a soft nose rest.
Compared to the large size of the instrument (90 x 55 mm), the technical holes and "windows" look very small: The air entrance is a 15 x 8 mm rectangle, and the mouth hole 15 x 6 mm.
Despite the raw hand carving, the airway exit is very thin and blows on a sharp angled labium.
On the sound side, all of these lead to a sweet but rather precise and quick sound, comparable to a wooden barrel organ, oriented towards the medium-bass. Despite its large size, the instrument by Don Luis is comfortable to play. The bevels designed for the hands-free cord are perfectly placed.
Here is a sound sample:
