When we pay attention to nature's music we find that every thing on the earth contributes to its harmony. The trees joyously wave their branches in rhythm with the wind; the sound of the sea, the murmuring of the breeze, the whistling of the wind through the rocks, hills and mountains, the flash of the lightning, and the crash of the thunder, the harmony of the sun and moon, the movements of the stars and planets, the blooming of the flower, the fading of the leaf, the regular alternation of morning, evening, noon and night - all reveal to the seer the music of nature.

The insects have their concerts and ballets, and the choirs of birds chant in unison their hymns of praise. Dogs and cats have their orgies, foxes and wolves have their soirees musicales in the forest, while tigers and lions hold their operas in the wilderness.

Music is the only means of understanding among birds and beasts. This may be seen by the gradation of pitch and volume of tone, the manner of tune, the number of repetitions, and the duration of their various sounds. These convey to their fellow-creatures the time for joining the flock, the warning of coming danger, the declaration of war, the feeling of love, and the sense of sympathy, displeasure, passion, anger, fear and jealousy - making a language of itself.
