The usual parallel chord in a major key is a minor third below the root and the counter parallel is a major third above. In a minor key the intervals are reversed: the tonic parallel (e.g. Eb in Cm) is a minor third above, and the counter parallel (e.g. Ab in Cm) is a major third below. Both the parallel and the counter parallel have two notes ...
The value of the two products in the chord theorem depends only on the distance of the intersection point S from the circle's center and is called the absolute value of the power of S; more precisely, it can be stated that: | | | | = | | | | =, where r is the radius of the circle, and d is the distance between the center of the circle and the ...
In music theory, contrapuntal motion is the general movement of two or more melodic lines with respect to each other. [1] In traditional four-part harmony, it is important that lines maintain their independence, an effect which can be achieved by the judicious use of the four types of contrapuntal motion: parallel motion, similar motion, contrary motion, and oblique motion.
A chord (from the Latin chorda, meaning "bowstring") of a circle is a straight line segment whose endpoints both lie on a circular arc. If a chord were to be extended infinitely on both directions into a line, the object is a secant line. The perpendicular line passing through the chord's midpoint is called sagitta (Latin for "arrow").

In music theory, a major scale and a minor scale that have the same starting note are called parallel keys and are said to be in a parallel relationship. [ 1 ] [ 2 ] For example, G major and G minor have the same tonic (G) but have different modes , so G minor is the parallel minor of G major.
Parallel harmony is frequently used in house music and other electronic music genres. Historically, this resulted from producers sampling chords from soul or jazz and then playing them at different pitches, or using "chord memory" feature from classic polyphonic synthesizers .
In just intonation, a minor chord is often (but not exclusively) tuned in the frequency ratio 10:12:15 (play ⓘ). In 12 tone equal temperament (12 TET, at present the most common tuning system in the West) a minor chord has 3 semitones between the root and third, 4 between the third and fifth, and 7 between the root and fifth.
