“Each animal fit into its own track, where it wouldn't overlap with and be muddied by the sounds of another. In a very real way, the animals were an orchestra: Each instrument made itself heard by producing a different set of frequencies. The elephants were the bass cellos, the hyenas the oboes, the hyraxes the clarinets, the insects the violins, and the bats the piccolos over the top.” NatureOrchestraFrequency Book:Unseen City: The Majesty of Pigeons, the Discreet Charm of Snails & Other Wonders of the Urban Wilderness Source: Unseen City: The Majesty of Pigeons, the Discreet Charm of Snails & Other Wonders of the Urban Wilderness
