According to Willi Apel, the earliest example of retrograde in music is the 13th century clausula, Nusmido, in which the tenor has the liturgical melody "Dominus" in retrograde (found in the manuscript Pluteo 29.1, folio 150 verso, located in the Laurentian Library in Florence). In music Nusmido, folio 150 verso of manuscript Pluteo 29.1, located in the Laurentian Library in Florence - the earliest known example of retrograde in musicĭespite not being mentioned in theoretical treatises prior to 1500, compositions written before that date show retrograde. Some writers acknowledge that hearing retrograde in music is a challenge, and consider it a self-referential compositional device. Friedrich Wilhelm Marpurg (1754) notes various names for the procedure imitatio retrograda or cancrizans or per motum retrogradum and says it is used primarily in canons and fugues. Thomas Morley (1597) described retrograde in the context of canons and mentions a work by Byrd. To tell the truth, a listening is more likely to be induced to vexation than to delight by these disproportioned fancies, which are devoid of pleasant harmony and contrary to the goal of the imitation of the nature of the words." He should not make a canon in the shape of a tower, a mountain, a river, a chessboard, or other objects, for these compositions create a loud noise in many voices, with little harmonic sweetness. In such cases a student can begin at the end and work back to the beginning in order to find where and in which voice he should begin the canons." Vicentino derided those who achieved purely intellectual pleasure from retrograde (and similar permutations): "A composer of such fancies must try to make canons and fugues that are pleasant and full of sweetness and harmony. Nicola Vicentino (1555) discussed the difficulty in finding canonic imitation: "At times, the fugue or canon cannot be discovered through the systems mentioned above, either because of the impediment of rests, or because one part is going up while another is going down, or because one part starts at the beginning and the other at the end. Retrograde was not mentioned in theoretical treatises prior to 1500. In twelve-tone music, reversal of the pitch classes alone-regardless of the melodic contour created by their registral placement-is regarded as a retrograde. Some composers choose to subject just the pitches of a musical line to retrograde, or just the rhythms. An even more exact retrograde reverses the physical contour of the notes themselves, though this is possible only in electronic music. An exact retrograde includes both the pitches and rhythms in reverse. This actually seems like good advice for any time of year, regardless of the apparent motion of any particular planets.A melodic line that is the reverse of a previously or simultaneously stated line is said to be its retrograde or cancrizans ( / ˈ k æ ŋ k r ɪ ˌ z æ n z/ "walking backward", medieval Latin, from cancer "crab"). Double check your email responses and check in with reservations before you take that trip.” “Try to remain flexible, patient, and understanding, allow extra time for travel, and avoid signing onto any new contracts that you’re unsure of. Meanwhile, the Farmer’s Almanac suggests that while Mercury is in retrograde, it’s good to take a moment to reflect: “There’s no scientific evidence that any planet’s apparent retrograde motion affects you at all,” Howells writes. After about three weeks of appearing to move backwards, Mercury will seem to start moving “forward” again.īut what does science have to say about the idea that these orbital patterns affect the flow of events on Earth? The current apparent retrograde phase for Mercury started on April 21 and will continue until May 14. The idea that a planet or moon could ever stop and totally reverse its actual course through the heavens or start spinning the opposite direction has yet to be observed and would likely be a remarkable and disruptive event (or the result of such an event). There’s also moons that orbit in a retrograde direction to most other satellites.īut this is just about being retrograde to a norm. For example, Venus rotates on its axis in retrograde motion to most other planets - the sun would rise there in the west and set in the east if it were ever not cloudy for a day. Sometimes, the phrase “retrograde” does refer to planetary bodies actually moving in the opposite direction of other bodies. In the astrology world, the phrase is shortened to simply “Mercury in retrograde,” which can be a little misleading, but most followers seem to acknowledge that the planet is not actually changing direction.
