You are familiar with some of Mother Nature's music already. Birds are the best at it, with human music and singing monkeys and other animals trailing behind. But there's natural music produced by non-living phenomena, if we take the time to properly harness and listen to it.
The stainless steel Venture Grant Aeolian Harp at the University of South Carolina has ten musical strings ranging up to 8 feet long connected to electronic pickups. Smaller Aeolian harps can be placed in windows or gardens. You can even make your own!
Different ways to make music with nature, after the jump.
The Great Stalacpipe Organ
The Great Stalacpipe Organ is the world's largest musical instrument, deep underground in Luray Caverns in Virginia. Rubber-tipped mallets tap the caves natural stalactites and produce musical tones. Stalactites that produce the exact tones needed cover 3.5 acres! Listen to the organ.
The Wave Organ
The Wave Organ, a part of the Exploratorium in San Francisco, is a concrete and granite seaside sculpture that include 25 organ pipes. The pipes are activated by the action of the waves.
The Sea Organ
The Sea Organ in Zadar, Croatia also uses the idea of wave-activated organ pipes. The 35 pipes beneath the steps are connected to whistle openings on top. The pipes are tuned to create harmonic chords instead of single notes. See and hear the effect at YouTube.
Musical tones are not limited to Mother Earth. Our sun has coils of electrified gas that carry acoustic waves. The effect is like plucking a guitar string, sending booms into the cosmos that dissipate within an hour. BLDGBLOG has more, with a link to an audio clip of the suns coronal booms.
Nature's music comes to us from even further away. A black hole in the Perseus Cluster is emitting sound waves. The tone is B flat, 57 octaves below middle C. What that may mean is anybody's guess.
