Oblique Motion
In music theory, contrapuntal motion is the general movement of two melodic lines with respect to each other. 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.Free-Ed.NeTraditional Harmony: Voice Motion Retrieved 2011-09-15. Parallel motion Parallel motion is motion in the same direction, keeping the same interval between them. For example : : Parallel motion at an interval of a perfect fifth is known as parallel or consecutive fifths, and at an interval of an octave is known as parallel or consecutive octaves. These motions are generally avoided in traditional counterpoint because they offer the lines so little independence from each other. Similar motion Similar motion is motion in the same direction, but with the interval between them changing. In other words, both lines mov ...

Music Theory
Music theory is the study of the practices and possibilities of music. ''The Oxford Companion to Music'' describes three interrelated uses of the term "music theory". The first is the " rudiments", that are needed to understand music notation (key signatures, time signatures, and rhythmic notation); the second is learning scholars' views on music from antiquity to the present; the third is a sub-topic of musicology that "seeks to define processes and general principles in music". The musicological approach to theory differs from music analysis "in that it takes as its starting-point not the individual work or performance but the fundamental materials from which it is built." Music theory is frequently concerned with describing how musicians and composers make music, including tuning systems and composition methods among other topics. Because of the ever-expanding conception of what constitutes music, a more inclusive definition could be the consideration of any sonic phenomena, ...

Horn Fifths
In music, consecutive fifths or parallel fifths are progressions in which the interval of a perfect fifth is followed by a ''different'' perfect fifth between the same two musical parts (or voices): for example, from C to D in one part along with G to A in a higher part. Octave displacement is irrelevant to this aspect of musical grammar; for example, a parallel twelfth (i.e., an octave plus a fifth) is equivalent to a parallel fifth.Thus, the word "parallel" is not truly synonymous with "consecutive", as a fifth followed by another fifth approached with contrary motion would still count as consecutive fifths. The term ''parallel fifths'' may therefore be misleading because some consecutive fifths occur with contrary motion: from a true uncompounded fifth to a twelfth, for example. If parts move by oblique motion (for example, one part moving from a C to a higher C, and another part repeating a G higher than both of those Cs), the intervals are not considered to differ in t ...

Harmony
In music, harmony is the process by which individual sounds are joined together or composed into whole units or compositions. Often, the term harmony refers to simultaneously occurring frequencies, pitches ( tones, notes), or chords. However, harmony is generally understood to involve both vertical harmony (chords) and horizontal harmony (melody). Harmony is a perceptual property of music, and, along with melody, one of the building blocks of Western music. Its perception is based on consonance, a concept whose definition has changed various times throughout Western music. In a physiological approach, consonance is a continuous variable. Consonant pitch relationships are described as sounding more pleasant, euphonious, and beautiful than dissonant relationships which sound unpleasant, discordant, or rough. The study of harmony involves chords and their construction and chord progressions and the principles of connection that govern them. Counterpoint, which refers to ...

Voice Leading
Voice leading (or part writing) is the linear progression of individual melodic lines ( voices or parts) and their interaction with one another to create harmonies, typically in accordance with the principles of common-practice harmony and counterpoint. Rigorous concern for voice leading is of greatest importance in common-practice music, although jazz and pop music also demonstrate attention to voice leading to varying degrees. In ''Jazz Theory'', Gabriel Sakuma writes that " the surface level, jazz voice-leading conventions seem more relaxed than they are in common-practice music."Terefenko, Dariusz (2014). ''Jazz Theory: From Basic to Advanced Study'', p. 33. Routledge. . Marc Schonbrun also states that while it is untrue that "popular music has no voice leading in it, ..the largest amount of popular music is simply conceived with chords as blocks of information, and melodies are layered on top of the chords."Schonbrun, Marc (2011).

Counterpoint
In music, counterpoint is the relationship between two or more musical lines (or voices) which are harmonically interdependent yet independent in rhythm and melodic contour. It has been most commonly identified in the European classical tradition, strongly developing during the Renaissance and in much of the common practice period, especially in the Baroque period. The term originates from the Latin ''punctus contra punctum'' meaning "point against point", i.e. "note against note". In Western pedagogy, counterpoint is taught through a system of species (see below). There are several different forms of counterpoint, including imitative counterpoint and free counterpoint. Imitative counterpoint involves the repetition of a main melodic idea across different vocal parts, with or without variation. Compositions written in free counterpoint often incorporate non-traditional harmonies and chords, chromaticism and dissonance. General principles The term "counterpoint" has bee ...

Drone (music)
In music, a drone is a harmonic or monophonic effect or accompaniment where a note or chord is continuously sounded throughout most or all of a piece. A drone may also be any part of a musical instrument used to produce this effect; an archaic term for this is ''burden'' (''bourdon'' or ''burdon'') such as a "drone ipeof a bagpipe", the pedal point in an organ, or the lowest course of a lute. Α ''burden'' is also part of a song that is repeated at the end of each stanza, such as the chorus or refrain.Brabner, John H F., ed. (1884). The national encyclopædia', Vol. V, p.99. Libr. ed. William McKenzie. . Musical effect "Of all harmonic devices, it droneis not only the simplest, but probably also the most fertile." A drone effect can be achieved through a sustained sound or through repetition of a note. It most often establishes a tonality upon which the rest of the piece is built. A drone can be instrumental, vocal or both. Drone (both instrumental and vocal) can be pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Interval (music)
In music theory, an interval is a difference in pitch between two sounds. An interval may be described as horizontal, linear, or melodic if it refers to successively sounding tones, such as two adjacent pitches in a melody, and vertical or harmonic if it pertains to simultaneously sounding tones, such as in a chord. In Western music, intervals are most commonly differences between notes of a diatonic scale. Intervals between successive notes of a scale are also known as scale steps. The smallest of these intervals is a semitone. Intervals smaller than a semitone are called microtones. They can be formed using the notes of various kinds of non-diatonic scales. Some of the very smallest ones are called commas, and describe small discrepancies, observed in some tuning systems, between enharmonically equivalent notes such as C and D. Intervals can be arbitrarily small, and even imperceptible to the human ear. In physical terms, an interval is the ratio between two sonic f ...

Melodic Inversion
In music theory, an inversion is a type of change to intervals, chords, voices (in counterpoint), and melodies. 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. Intervals An interval is inverted by raising or lowering either of the notes by one or more octaves so that the positions of the notes reverse (i.e. the higher note becomes the lower note and vice versa). For example, the inversion of an interval consisting of a C with an E above it (the third measure below) is an E with a C above it – to work this out, the C may be moved up, the E may be lowered, or both may be moved. : The tables to the right show the changes in interval quality and interval number under inversion. Thus, perfect intervals remain perfect, major intervals become minor and vice versa, and augmented intervals become diminished and vice versa. (Doubly diminished intervals become doubly augmen ...

Melodic Motion
Melodic motion is the quality of movement of a melody, including nearness or farness of successive pitches or notes in a melody. This may be described as conjunct or disjunct, stepwise, skipwise or no movement, respectively. See also contrapuntal motion. In a conjunct melodic motion, the melodic phrase moves in a stepwise fashion; that is the subsequent notes move up or down a semitone or tone, but no greater. In a disjunct melodic motion, the melodic phrase leaps upwards or downwards; this movement is greater than a whole tone. In popular Western music, a melodic leap of disjunct motion is often present in the chorus of a song, to distinguish it from the verses and captivate the audience. Bruno Nettl describes various types of melodic movement or contour (Nettl 1956, 51–53): *Ascending: Upwards melodic movement *Descending: Downwards melodic movement (prevalent in the New World and Australian music) *Undulating: Equal movement in both directions, using approximately the same ...
