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.
In 1882 Germany, Austria-Hungary and Italy formed the Triple Alliance. The three countries agreed to support each other if attacked by either France or Russia. France felt threatened by this alliance. Britain was also concerned by the growth in the German Navy and in 1904 the two countries signed the Entente Cordiale (friendly understanding).
