Aerophones or wind instruments produce sound by the means of vibrating air. In free aerophones, the vibrating air is free, not in a closed tube or body. The rest of aerophones have an air tube or container and have different systems to activate it; flutes (with a bevel or sharp edge), aerophones with reeds (single or double) and lip vibration instruments (trumpet type) are distinguished.
In the classification of the German musicologists Erich von Hornbostel and Curt Sachs, aerophones make up the fourth of the five groups of instruments.
