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.
Sociomusicology (from Latin: socius, "companion"; from Old French musique; and the suffix -ology, "the study of", from Old Greek λόγος, lógos : "discourse"), also called music sociology or the sociology of music, refers to both an academic subfield of sociology that is concerned with music (often in combination with other arts), as well as a subfield of musicology that focuses on social ...
Descant is a type of medieval polyphony characterized by relatively strict note-for-note counterpoint.It is found in the organum with a plainchant tenor (i.e. low voice; vox principis), and in the conductus without the requirement of a plainchant tenor.
Traditional sub-Saharan African harmony is a music theory of harmony in sub-Saharan African music based on the principles of homophonic parallelism (chords based around a leading melody that follow its rhythm and contour), homophonic polyphony (independent parts moving together), counter-melody (secondary melody) and ostinato-variation (variations based on a repeated theme).
A Landini cadence (Landini sixth or Landini sixth cadence), or under-third cadence, [4] is a type of cadence, a technique in music composition, named after Francesco Landini (1325–1397), an influential Italian composer, in honor of his extensive use of the technique. The technique was used extensively in the 14th and early 15th century.
Contrary motion should dominate. Perfect consonances must be approached by oblique or contrary motion. Imperfect consonances may be approached by any type of motion. The interval of a tenth should not be exceeded between two adjacent parts unless by necessity. Build from the bass, upward.
In music theory, an inversion is a rearrangement of the top-to-bottom elements in an interval, a chord, a melody, or a group of contrapuntal lines of music. [2] In each of these cases, "inversion" has a distinct but related meaning. The concept of inversion also plays an important role in musical set theory.
The mirror canon (also called a canon by contrary motion) is a type of canon which involves the leading voice being played alongside its own inversion (i.e. upside-down). The realisation from the 'closed' (unrealised) form can be effected by placing the page in front of a mirror, thus upside down, and beginning with the already progressing ...
