A brass aerophone is a musical instrument that produces sound by sympathetic vibration of air in a tubular resonator in sympathy with the vibration of the player's lips. Brass instruments are also called labrosones, literally meaning lip-vibrated instruments.
By Robert Wilde. By 1914, the six major powers of Europe were split into two alliances, which would â with the exception of Italy â form the two warring sides in World War One. Britain, France and Russia were in the Triple Entente, while Germany, Austria-Hungary and Italy were in the Triple Alliance.
On one side, we have Germany, Austria-Hungary, and Italy, which formed the Triple Alliance. Germany and Austria-Hungary were already allies by 1879 when, worried about a threat from Russia, they formed the Dual Alliance. Italy joined the group in 1882.
