singing

Singing is the act of producing musical sounds with the voice, which is often contrasted with speech. Contrary to common thought, air is not expelled with the diaphragm, but is inhaled using the diaphragm and exhaled or expelled, using the abdominal and lower pelvic muscles, as with ordinary breathing. The pitch is altered with the vocal cords. With the lips closed, this is called humming. A piece of music with a singing part, either acappella or accompanied, is called a song; someone who sings is called a singer.

To hear singing in your dreams, betokens a cheerful spirit and happy companions. You are soon to have promising news from the absent.

If you are singing while everything around you gives promise of happiness, jealousy will insinuate a sense of insincerity into your joyousness. If there are notes of sadness in the song, you will be unpleasantly surprised at the turn your affairs will take.

Ribald songs, signifies gruesome and extravagant waste.
