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 Entente consisted of Great Britain, France and Russia. It was formed through a variety of different diplomatic agreements and treaties between the three countries in the late 19th and early 20th centuries, and helped smooth over previous rivalries the three countries had with one another.
