Aerophone It is an adjective that, according to the dictionary of the Royal Spanish Academy (RAE ), is used to qualify wind instruments . An aerophone, therefore, is a musical instrument whose sound is generated from the vibrations of the air, without the need to use membranes or strings .

Inside, an aerophone instrument houses a certain amount of air which, when excited, produces a sound. This sound depends on the volume of the gas, not on the characteristics of the container that provides containment. What this container does (the structure of the instrument) is to establish the form that the volume of the gas will take and, by extension, determine how it sounds.

It is considered that the origin of the aerophones is very ancient. So much so that it is established that the first examples of these wind musical instruments would be the horns of the animals, the conches and even the trunks that had been emptied inside.

Then, as the story evolved, others appeared somewhat more "sophisticated" as, for example, the so-called mirlitons or flutes of the shepherds.

The wooden aerophones offer a sound Soft bell. The musician must blow through a hole or generate the vibration of a tongue. The sweet flute , the quena and the erke They are examples of wooden aerophones.

As for the metal aerophones , produce a loud ringing sound. In this case, the musician makes his lips vibrate in a mouthpiece that generates the acoustic frequency. Among the metal aerophones we can name the trumpet , the tuba and the trombone .

There are other ways to rate aerophones. According to the shape of their tubes, they can be prismatic, cylindrical or conical. Regarding the method of obtaining the scale , there are aerophones with tubes of variable length and aerophones with tubes that have holes.

If we focus on the excitement of the column from the air, we find nozzle aerophones (the trumpet), tongue aerophones (the harmonica) and mouthpiece aerophones (the flute).

In addition to all of the above, we cannot ignore the fact that in certain countries there are aerophones that are typical and traditional, while very characteristic. Thus, for example, we can highlight the following:
-In the Basque Country is the famous chistu.
-In the Andalusian province of Huelva, what is called flute rociera takes on special relevance. This, as its name suggests, is the typical one that is played when the pilgrims make their way from their home cities to the village of El Rocío, where the Virgin of the same name is located.
-In several autonomous communities in Spain, Dulzaina is very characteristic, which has a particularly high-pitched sound and is identified by being made with wood, yes, in each region with a different one.

In addition to all of the above, we can point out these other relevant issues:
- The larger the diameter of the tube, the more serious the sound will be.
-The longer the tube is, the louder the sound will also be. And this will also be more serious the higher the air pressure.
