- Military–industrial complex (Wikipedia)
The expression military–industrial complex (MIC) describes the relationship between a country’s military and the defense industry that supplies it, seen together as a vested interest which influences public policy. A driving factor behind the relationship between the military and the defense-minded corporations is that both sides benefit—one side from obtaining weapons, and the other from being paid to supply them. The term is most often used in reference to the system behind the armed forces of the United States, where the relationship is most prevalent due to close links among defense contractors, the Pentagon, and politicians. The expression gained popularity after a warning of the relationship’s detrimental effects, in the farewell address of U.S. President Dwight D. Eisenhower on January 17, 1961.
- Canon (music) (Wikipedia)
In music, a canon is a contrapuntal (counterpoint-based) compositional technique that employs a melody with one or more imitations of the melody played after a given duration (e.g., quarter rest, one measure, etc.). The initial melody is called the leader (or dux), while the imitative melody, which is played in a different voice, is called the follower (or comes). The follower must imitate the leader, either as an exact replication of its rhythms and intervals or some transformation thereof. Repeating canons in which all voices are musically identical are called rounds—familiar singalong versions of “Row, Row, Row Your Boat” and “Frère Jacques” that call for each successive group of voices to begin the same song a bar or two after the previous group began are popular examples.
