Duration (music)
In music, duration is an amount of time or how long or short a note, phrase, section, or composition lasts. "''Duration'' is the length of time a pitch, or tone, is sounded." A note may last less than a second, while a symphony may last more than an hour. One of the fundamental features of rhythm, or encompassing rhythm, duration is also central to meter and musical form. Release plays an important part in determining the timbre of a musical instrument and is affected by articulation. The concept of duration can be further broken down into those of beat and meter, where beat is seen as (usually, but certainly not always) a 'constant', and rhythm being longer, shorter or the same length as the beat. In serial music the beginning of a note may be considered, or its duration may be (for example, is a 6 the note which begins at the sixth beat, or which lasts six beats?). Durations, and their beginnings and endings, may be described as long, short, or taking a specific amount ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scale (measurement)
Level of measurement or scale of measure is a classification that describes the nature of information within the values assigned to dependent and independent variables, variables. Psychologist Stanley Smith Stevens developed the best-known classification with four levels, or scales, of measurement: #Nominal level, nominal, #Ordinal scale, ordinal, #Interval scale, interval, and #Ratio scale, ratio. This framework of distinguishing levels of measurement originated in psychology and has since had a complex history, being adopted and extended in some disciplines and by some scholars, and criticized or rejected by others. Other classifications include those by Mosteller and John Tukey, Tukey, and by Chrisman. Stevens's typology Overview Stevens proposed his typology in a 1946 ''Science (journal), Science'' article titled "On the theory of scales of measurement". In that article, Stevens claimed that all measurement in science was conducted using four different types of scales tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tuplet
In music, a tuplet (also irrational rhythm or groupings, artificial division or groupings, abnormal divisions, irregular rhythm, gruppetto, extra-metric groupings, or, rarely, contrametric rhythm) is "any rhythm that involves dividing the beat into a different number of equal subdivisions from that usually permitted by the time-signature (e.g., triplets, duplets, etc.)" This is indicated by a number, or sometimes two indicating the fraction involved. The notes involved are also often grouped with a bracket or (in older notation) a slur. The most common type of tuplet is the triplet. Terminology The modern term 'tuplet' comes from a rebracketing of compound words like quintu(s)-(u)plet and sextu(s)-(u)plet, and from related mathematical terms such as "tuple", "-uplet" and "-plet", which are used to form terms denoting multiplets (''Oxford English Dictionary'', entries "multiplet", "-plet, ''comb. form''", "-let, ''suffix''", and "-et, ''suffix''1").

Amphibrach
An amphibrach () is a metrical foot used in Latin and Greek prosody. It consists of a long syllable between two short syllables. The word comes from the Greek ἀμφίβραχυς, ''amphíbrakhys'', "short on both sides". Usage English In English accentual-syllabic poetry, an amphibrach is a stressed syllable surrounded by two unstressed syllables. It is rarely used as the overall meter of a poem, usually appearing only in a small amount of humorous poetry, children's poetry, and experimental poems. The individual amphibrachic foot often appears as a variant within, for instance, anapaestic meter. It is the main foot used in the construction of the limerick, as in "There once was / a girl from / Nantucket." It was also used by the Victorians for narrative poetry, e.g. Samuel Woodworth's poem "The Old Oaken Bucket" (1817) beginning "How dear to / my heart are / the scenes of / my childhood." W. H. Auden's poem "O where are you going?" (1931) is a more recent and slightl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dactyl (poetry)
A dactyl (; from Greek ) is a foot in poetic meter. In quantitative verse, often used in Greek or Latin, a dactyl is a long syllable followed by two short syllables, as determined by syllable weight. The best-known use of dactylic verse is in the epics attributed to the Greek poet Homer, the ''Iliad'' and the ''Odyssey''. In accentual verse, often used in English, a dactyl is a stressed syllable followed by two unstressed syllables—the opposite is the anapaest (two unstressed followed by a stressed syllable). An example of dactylic meter is the first line of Henry Wadsworth Longfellow's epic poem '' Evangeline'' (1847), which is in dactylic hexameter: :''This is the / forest prim- / eval. The / murmuring / pines and the / hemlocks, The first five feet of the line are dactyls; the sixth a trochee. Stephen Fry quotes Robert Browning's poem " The Lost Leader" as an example of the use of dactylic metre to great effect, creating verse with "great rhythmic dash and drive": ...

Trochee
In poetic metre, a trochee ( ) is a metrical foot consisting of a stressed syllable followed by an unstressed syllable, unstressed one, in qualitative meter, as found in English, and in modern linguistics; or in quantitative meter, as found in Latin and Ancient Greek, a heavy syllable followed by a light one (also described as a long syllable followed by a short one). In this respect, a trochee is the reverse of an iamb (poetry), iamb. Thus the Latin word , because of its short-long rhythm, in Latin metrical studies is considered to be an iamb, but since it is stressed on the first syllable, in modern linguistics it is considered to be a trochee. The adjective form is ''trochaic''. The English word ''trochee'' is itself trochaic since it is composed of the stressed syllable followed by the unstressed syllable . Another name formerly used for a trochee was a choree ( ) or choreus. Etymology ''Trochee'' comes from French language, French , adapted from Latin , originally from ...

Anapest
An anapaest (; also spelled anapæst or anapest, also called antidactylus) is a metrical foot used in formal poetry. In classical quantitative meters it consists of two short syllables followed by a long one; in accentual stress meters it consists of two unstressed syllables followed by one stressed syllable. It may be seen as a reversed dactyl. This word comes from the Greek , ''anápaistos'', literally "struck back" and in a poetic context "a dactyl reversed". Because of its length and the fact that it ends with a stressed syllable and so allows for strong rhymes, anapaest can produce a very rolling verse, and allows for long lines with a great deal of internal complexity. Apart from their independent role, anapaests are sometimes used as substitutions in iambic verse. In strict iambic pentameter, anapaests are rare, but they are found with some frequency in freer versions of the iambic line, such as the verse of Shakespeare's last plays, or the lyric poetry of the 19th centur ...

Iamb (foot)
An iamb ( ) or iambus is a metrical foot used in various types of poetry. Originally the term referred to one of the feet of the quantitative meter of classical Greek prosody: a short syllable followed by a long syllable (as in () "beautiful (f.)"). This terminology was adopted in the description of accentual-syllabic verse in English, where it refers to a foot comprising an unstressed syllable followed by a stressed syllable (as in ''abóve''). Thus a Latin word like , because of its short-long rhythm, is considered by Latin scholars to be an iamb, but because it has a stress on the first syllable, in modern linguistics it is considered to be a trochee. Etymology R. S. P. Beekes has suggested that the ''iambos'' has a Pre-Greek origin. An old hypothesis is that the word is borrowed from Phrygian or Pelasgian, and literally means "Einschritt", i. e., "one-step", compare ''dithyramb'' and '' thriambus'', but H. S. Versnel rejects this etymology and suggests instead a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metrical Feet
The foot is the basic repeating rhythmic unit that forms part of a line of verse in most Indo-European traditions of poetry, including English accentual-syllabic verse and the quantitative meter of classical ancient Greek and Latin poetry. The unit is composed of syllables, and is usually two, three, or four syllables in length. The most common feet in English are the iamb, trochee, dactyl, and anapaest. The foot might be compared to a bar, or a beat divided into pulse groups, in musical notation. A metrical foot is, in classical poetry, a combination of two or more short or long syllables in a specific order; although this "does not provide an entirely reliable standard of measurement" in heavily accented Germanic languages such as English. In these languages it is defined as a combination of one stressed and one or two unstressed syllables in a specific order. In general, lines of verse can be classified according to the number of feet they contain, using the terms m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhythmic Gesture
Rhythm (from Greek , ''rhythmos'', "any regular recurring motion, symmetry") generally means a " movement marked by the regulated succession of strong and weak elements, or of opposite or different conditions". This general meaning of regular recurrence or pattern in time can apply to a wide variety of cyclical natural phenomena having a periodicity or frequency of anything from microseconds to several seconds (as with the riff in a rock music song); to several minutes or hours, or, at the most extreme, even over many years. The Oxford English Dictionary defines rhythm as ''"The measured flow of words or phrases in verse, forming various patterns of sound as determined by the relation of long and short or stressed and unstressed syllables in a metrical foot or line; an instance of this"''. Rhythm is related to and distinguished from pulse, meter, and beats: In the performance arts, rhythm is the timing of events on a human scale; of musical sounds and silences that occur ove ...

Tempo
In musical terminology, tempo (Italian for 'time'; plural 'tempos', or from the Italian plural), measured in beats per minute, is the speed or pace of a given musical composition, composition, and is often also an indication of the composition's character or atmosphere. In classical music, tempo is typically indicated with an instruction at the start of a piece (often using conventional Italian terms) and, if a specific metrical pace is desired, is usually measured in beat (music), beats per minute (bpm or BPM). In modern classical compositions, a "metronome mark" in beats per minute, indicating only measured speed and not any form of expression, may supplement or replace the normal tempo marking, while in modern genres like electronic dance music, tempo will typically simply be stated in bpm. Tempo (the underlying pulse of the music) is one of the three factors that give a piece of music its texture (music), texture. The others are meter (music), meter, which is indicated by a ...
