an aside

A brief respite from the elegant line of reasoning being presented on music and chemistry... but not unrelated.

Giant Pipe Organ In The Solar Atmosphere

Science Daily Astronomers have found that the atmosphere of the Sun plays a kind of heavenly music. The magnetic field in the outer regions (the corona) of our nearest star forms loops that carry waves and behave rather like a musical instrument.

The acoustic waves can be extremely powerful and reach amplitudes of tens of kilometres per second. Professor von Fay-Siebenburgen adds, “we found that the waves are often generated at the base of the magnetic pipes by enormous explosions known as micro-flares. These release energy equivalent to millions of hydrogen bombs. After each micro-flare, sound booms are rapidly excited inside the magnetic pipes before decaying in less than an hour and dissipating in the very hot solar corona.”
