MAJOR, in logic, is understood of the first proposition of a regular syllogism. It is called major, because it has a more extensive sense than the minor proposition, as containing the principal term. See LOGIC.
MAJOR and MINOR, in music, are applied to concords which differ from each other by a semi-tone. See CONCORD.
Major tone is the difference between the fifth and fourth; and major semi-tone the difference between the major fourth and the third. The major tone surpasses the minor by a comma.
