It is the wind that brings wind instruments to resonate.
How wind instruments and their music developed? From Turkish bands around 1800 to the orchestral instruments of the 19th century, the invention of the saxophone around 1840, as well as how a simple shepherd's horn became a beloved instrument of traditional and modern music, as well as a symbol of Swissness: the Alphorn.
And you can try to play some of the instruments by yourself: Alphorns, Roman cornua, contrabass trombone an more.
