Then Herod saw that he had been tricked by the astrologers, and he was very angry, and he sent and made away with all the boys in Bethlehem and in all that neighborhood who were two years old or under, for that was the tune he had learned from the astrologers by his inquiries.

"if we play a merry tune, you are not for dancing; if we act a mournful part, you are not in the humour."

Even inanimate things, like the flute or the harp, may give out sounds, but if there is no difference in the notes, how can the tune that is played on the flute or the harp be told?
