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.
The Triple Alliance or Triplice was a secret agreement between Germany, Austria-Hungary, and Italy. It was formed on 20 May 1882 and renewed periodically until it expired in 1915 during World War I. Germany and Austria-Hungary had been closely allied since 1879. Italy sought support against France shortly after it lost North African ambitions to the French. Each member promised mutual support in the event of an attack by any other great power.
