Research in the field of bioacoustics has revealed that every day we are surrounded by millions of ultrasonic songs. Did you know, for instance, that the electron shell of the carbon atom produces the same harmonic scale as the Gregorian chant? Or that whale songs can travel thousands of miles underwater? Or that meadowlarks have a range of three hundred notes? Supersensitive sound instruments have discovered that even earthworms make faint staccato sounds! Arnold Summerfield, the German physicist and pianist, observed that a single hydrogen atom, which emits one hundred frequencies, is more musical than a grand piano, which only emits eighty-eight frequencies.

Science writer Lewis Thomas summed it up it this way: "If we had better hearing, and could discern the [singing] of sea birds, the rhythmic [drumming] of schools of mollusks, or even the distant harmonics of [flies] hanging over meadows in the sun, the combined sound might lift us off our feet."
