Hence we speak of the intermediate as in a sense a contrary relatively to the extremes and of either extreme as a contrary relatively to the intermediate: for instance, the central note is low relatively-to the highest and high relatively to the lowest, and grey is light relatively to fl and dark relatively to white.
Motion in respect of Quantity has no name that includes both contraries, but it is called increase or decrease according as one or the other is designated: that is to say motion in the direction of complete magnitude is increase, motion in the contrary direction is decrease.
And wherever a pair of contraries admit of an intermediate, motions to that intermediate must be held to be in a sense motions to one or other of the contraries: for the intermediate serves as a contrary for the purposes of the motion, in whichever direction the change may be, e.g.

 [No title]
Nor again can motion along the circle from A to B be regarded as the contrary of motion from A to C: for the motion goes from the same point towards the same point, and contrary motion was distinguished as motion from a contrary to its contrary.
And even if the motion round a circle is the contrary of the reverse motion, one of the two would be ineffective: for both move to the same point, because that which moves in a circle, at whatever point it begins, must necessarily pass through all the contrary places alike.
Motion upward and downward and sideways were all, they thought, equally inappropriate to that which is set at the centre and indifferently related to every extreme point; and to move in contrary directions at the same time was impossible: so it must needs remain still.

 Contrary motion - Wikipedia, the free encyclopedia
In music theory, contrary motion is the general movement of two melodic lines or pitches in opposite directions.
For example, in one melodic line a note moving to another of a higher pitch, a second line in contrary motion would have this note moving to another of a lower pitch at the same time.
The concept of contrary motion is important in the analysis of musical themes.

 ON THE HEAVENS by Aristotle
For example, taking a complete circle, motion from E to F on the semicircle G may be opposed to motion from F to E on the semicircle H. But even supposing these are contraries, it in no way follows that the reverse motions on the complete circumference contraries.
Again, if the motion of the heaven is the measure of all movements whatever in virtue of being alone continuous and regular and eternal, and if, in each kind, the measure is the minimum, and the minimum movement is the swiftest, then, clearly, the movement of the heaven must be the swiftest of all movements.
Motion upward and downward and sideways were all, they thought, equally inappropriate to that which is set at the centre and indifferently related to every extreme point; and to move in contrary directions at the same time was impossible: so it must needs remain still.

 Aristotle - The Organon CATEGORIES 1 14 Affection   (Site not responding. Last check: )
Thus alteration is a distinct sort of motion; for, if it were not, the thing altered would not only be altered, but would forthwith necessarily suffer increase or diminution or some one of the other sorts of motion in addition; which as a matter of fact is not the case.
But the different forms of motion have their own contraries in other forms; thus destruction is the contrary of generation, diminution of increase, rest in a place, of change of place.
It appears to have no contrary, unless one should define the contrary here also either as 'rest in its quality' or as 'change in the direction of the contrary quality', just as we defined the contrary of change of place either as rest in a place or as change in the reverse direction.

 Canon: Anatomy of
In the context of canons, the term "inverted canon" is synonymous with "canon in contrary motion." Canons in contrary motion exemplify the technique of "melodic inversion," and should not be confused with contrapuntal inversion (also known as "double counterpoint") in which two contrapuntal lines exchange registers...the low becoming the high and visa versa.
Notice that canons in contrary motion are normally constructed so that if the leader begins on the tonic pitch the follower will begin on the dominant, and visa versa.
Because inverting a C-clef effects no apparent change, contrary motion is signified by the inversion of key signatures or by the placement of accidentals on "wrong" lines and spaces.

 [No title]   (Site not responding. Last check: )
If it is the nature of earth, as observation shows, to move from any point to the centre, as of fire contrariwise to move from the centre to the extremity, it is impossible that any portion of earth should move away from the centre except by constraint.
For a single thing has a single movement, and a simple thing a simple: contrary movements cannot belong to the same thing, and movement away from the centre is the contrary of movement to it.
Therefore earth in motion, whether in a mass or in fragments, necessarily continues to move until it occupies the centre equally every way, the less being forced to equalize itself by the greater owing to the forward drive of the impulse.

 Thirteenth-Century Polyphony - Directed cadences
In the third case, only the lower third resolves by stepwise contrary motion (3-5), the upper third resolving by similar motion to the upper fourth of the trine.
In another resolution by contrary motion, the major ninth expands to a twelfth while the lower fifth expands to an octave, arriving at a 12/8 sonority.
In the case of 5/4 and 5/2, however, resolutions by directed contrary motion as well as oblique motion play a significant role in the cadential lexicon of the 13th century.

 species counterpoint : melodic inversion : contrary motion
Permitted melodic intervals are the perfect fourth, fifth, and octave, as well as the major and minor second, major and minor third, and ascending minor sixth.
The interval of a tritone in three notes is to be avoided (for example, an ascending melodic motion F - A - B natural), as is the interval of a seventh in three notes.
Avoid parallel fifths or octaves between any two parts; and avoid "hidden" parallel fifths or octaves: that is, movement by similar motion to a perfect fifth or octave, unless one part (sometimes restricted to the higher of the parts) moves by step.

Finally the C over the last chord shows that the doubling between bass and tenor is approached in contrary motion.

 Aristotle, On the Heavens   (Site not responding. Last check: )
Now revolution about the center is circular motion, while the upward and downward movements are in a straight line, ‘upward’ meaning motion away from the center, and ‘downward’ motion towards it.
This conclusion that local movement is not continued to infinity is corroborated by the fact that earth moves more quickly the nearer it is to the center, and fire the nearer it is to the upper place.
Motion upward and downward and sideways were all, they thought, equally inappropriate to that which is set at the center and indifferently related to every extreme point; and to move in contrary directions at the same time was impossible: so it must needs remain still.

Move to a perfect consonance in oblique or contrary motion -- never in direct motion (direct motion means both similar and parallel motion).
Avoid "beaten" (batutta) octave, fifth, and unison -- approach to any of these perfect consonances by contrary motion with a leap in the upper voice.
Use oblique motion or suspensions in approach to the downbeat as much as possible "since it brings about the greatest beauty in the counterpoint."

 Objectionable Motion
Some kinds of parallel motion must not occur except under appropriate harmonic circumstances because they destroy the four part texture: octaves, unisons, perfect fifths, and parallel dissonant intervals.
When two parts move in similar motion to a unison, perfect fifth, or perfect octave, that movement is called Hidden or Covered.
Parallels by contrary motion occur when two voices move by contrary motion from one harmonic interval to the same harmonic interval.

 Music in Contrary Motion, Philip Glass
Contrary Motion, composed in 1969, is a work for solo organ in which pedal points add a functional harmony (A minor) and there is something faintly Bach-ian about its stern, rigorous counterpoint.
Contrary Motion was written in what Glass calls "open form" — it never really ends, it just stops.
The expanding figures upon which it is constructed could, theoretically, continue augmenting forever.
