-pabellon:This one is soldier to the superior cane; Is of the number twenty-four brass; Has a length of seven centimeters, with the shape of a truncated cone, which at the base has a circumference of twenty four centimeters, which ends in a cord made with the same blade to give greater resistance to the edge, and at the vertex Circumference is approximately four centimeters with eight millimeters.
-Superior Can:It is located behind the pavilion attached to it by means of welding; Has a length of approximately seventy-three centimeters; Is also of conical form, being its greater diameter of forty and eight millimeters. Approximately in the middle, it curves with a opening of ten centimeters, thus giving beginning to the first return of the cornet. It is attached to the lower shaft by means of welding and the bushing; By the outer side of the curve has joined by means of welding, the chavacote and exactly below this one by the inner side, is located one of the rings.

At about eight centimeters, it is curved in semicircular form, with an opening of nine centimeters and a half and in the inner part of the curve has joined by means of welding the other ring.
-Accommodation: This piece, together with the tudel, are the only ones on the cornet completely straight; It measures fifteen centimeters and a half, with an inner diameter of twelve millimeters; At the front end and what is where the horn ends, has a welded seam with a clamp which has two rings, one of them threaded with a cord of 3/16, which serve to introduce the butterfly, which when pressed holds the tudel in Position for proper tuning.
-Tudel:Es un tubo de quince centímetros de largo, con un diámetro de once punto milímetros, el extremo opuesto, o sea donde se introduce la boquilla, tiene soldada una abrazadera con orejas cuyo fin es el dar mayor resistencia en esa parte a la pieza y las orejas facilitan el manejo de la misma.

The throat is located where the cup ends and the nozzle body begins. The body is conical in shape, both internally and externally; Begins in the grain and ends with a diameter of eight millimeters.
-Hoops: They are of brass wire of the number eight, have a diameter of fifteen millimeters, are welded to bases of circular form in the superior cane as in the inferior one; These pieces serve to secure the garment in the horn.
-Chavacote: It is a piece of the same material as the horn, it has a length of thirteen centimeters and in the form of an extended dude; Is connected to the upper rod by means of welding and serves to reinforce said rod in the curve on the outer side thereof.
