Volcano music

Holiday on Tenerife made me wonder what a volcano sounds like. It's different from a mountain- it's not green, no yodeling going on, no hunters sounding their horns. Hardly anything lives there, hardly anything sounds there. It's rock in every imaginable colour: from deep black to red, yellow and even soapy green. The clouds roll over the crater rim in an eerie silence. Yet, there's an immense sense of energy hidden just below the surface, waiting to happen.

Music-wise, I wondered whether anyone had ever written anything specifically on volcanoes. A Google-search pointed me to Alan Hovhaness, an American composer who composed a symphony on the eruption of Mount St Helens.

And what do you know: volcanoes themselves make music too. At least, according to Italian researchers who plotted seismic activity of Mt. Etna and Tungurahua (Equador) to music bars.
