context_page_description: A musical line which is the reverse of a previously or simultaneously stated line is said to be its retrograde or cancrizans. An exact retrograde includes both the pitches and rhythms in reverse. An even more exact retrograde reverses the physical contour of the notes themselves, though this is possible only in electronic music. Some composers choose to subject just the pitches of a musical line to retrograde, or just the rhythms. 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.
context_section_description: Despite not being mentioned in theoretical treatises prior to 1500, compositions written before that date show retrograde. 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). (The word "Nusmido" is a syllabic retrograde of the word "Dominus.")
  
  Surveying medieval examples of retrograde, Virginia Newes notes that early composers were often also poets, and that musical retrogrades could have been based on similarly constructed poetic texts. She quotes Daniel Poirion in suggesting that the retrograde canon in Machaut's three-voice rondeau, "Ma Fin est mon Commencement" could symbolize a metaphysical view of death as rebirth, or else the ideal circle of the courtly outlook, which encloses all initiatives and all ends. She concludes that, whatever the reasons, construction of retrogrades and their transmission were part of the medieval composers' world, as they prized symmetry and balance as intellectual feats in addition to the aural experience. 
  Todd notes that although some composers (John Dunstaple, Guillaume Dufay and Johannes Ockeghem) used retrograde occasionally, they did not combine it with other permutations. In contradistinction, Antoine Busnois and Jacob Obrecht, used retrograde and other permutations extensively, suggesting familiarity with one another's compositional techniques. Todd also notes that, by use of retrograde, inversion, and retrograde-inversion, composers of this time viewed music in a way similar to serialists of the 20th century.
  However, as Edmund Rubbra (1960, p. 35) points out, “This is, of course, a purely mental concept, as music can never do anything but go forwards, even if the given tune is reversed.  The different relationships set up by reversing the direction of a theme make it completely unrecognizable; and when a composer indulges in this device the disclosure of it makes not the slightest difference to our apprehension of the music, which must be listened to as going parallel with the time-processes of our existence.”
  
  Nevertheless, there are examples of retrograde motion in the music of J.S. Bach, Haydn and Beethoven.  Bach’s Musical Offering includes a two-voice canon in which the second voice performs the melodic line of first voice backwards:
  The minuet (third) movement of Joseph Haydn’s, Symphony no. 47,  is an exact palindrome. Haydn also transcribed this piece for piano and this version forms the second movement of his Piano Sonata in A major XVI/26 
  
  The fugal fourth movement of Beethoven, Piano Sonata no. 29, op. 106, "Hammerklavier", has the following main theme:
  Later in this movement, Beethoven conjures up and uses the retrograde version of the subject. Beethoven does not create a strict note-for-note reversal of the theme.
