Melody

Singing a melody signifies false speech and calamity. If the singer's voice is beautiful, it signifies beneficial trade; if unpleasant, harmful trade. Singing badly signifies misery and humiliation, and singing in general may signify evil and quarrelling. The exception given is singing harmoniously while traveling along a road, which the source treats as good and as a sign of joy.

Seeing oneself sing beautiful melodies, or hearing them from someone else, signifies serenity of heart, joy, and happiness.
