Pulse (music)
In music theory, the pulse is a series of uniformly spaced beats—either audible or implied that sets the tempo and is the scaffolding for the rhythm. By contrast, rhythm is always audible and can depart from the pulse. So while the rhythm may become too difficult for an untrained listener to fully match, nearly any listener instinctively matches the pulse by simply tapping uniformly, despite rhythmic variations in timing of sounds atop the pulse.Fitch, W. Tecumseh and Rosenfeld, Andrew J. (2007). Definitions The pulse may be audible or implied. The tempo of the piece is the speed of the pulse. If a pulse becomes too fast it would become a drone; one that is too slow would be perceived as unconnected sounds.P. Fraisse, ''Les Structures Rhythmiques'', Erasme Paris 1956, H Woodrow ''Time Perception'' in "A Handbook of Experimental Psychology", ed. S.S.

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, ...

Metre (music)
In music, metre ( Commonwealth spelling) or meter (American spelling) refers to regularly recurring patterns and accents such as bars and beats. Unlike rhythm, metric onsets are not necessarily sounded, but are nevertheless implied by the performer (or performers) and expected by the listener. A variety of systems exist throughout the world for organising and playing metrical music, such as the Indian system of '' tala'' and similar systems in Arabic and African music. Western music inherited the concept of metre from poetry, where it denotes: the number of lines in a verse; the number of syllables in each line; and the arrangement of those syllables as long or short, accented or unaccented. The first coherent system of rhythmic notation in modern Western music was based on rhythmic modes derived from the basic types of metrical unit in the quantitative metre of classical ancient Greek and Latin poetry. Later music for dances such as the pavane and galliard consisted of m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sextuple Metre
Sextuple metre (Am. meter) or sextuple time (chiefly British) is a musical metre characterized by six beats in a measure. Like the more common duple, triple, and quadruple metres, it may be simple, with each beat divided in half, or compound, with each beat divided into thirds. The most common time signatures for simple sextuple metre are and , and compound sextuple metre is most often written in or . A time signature of or , however, does not necessarily mean that the bar is a sextuple metre with each beat divided into three. It may, for example, be used to indicate a bar of triple metre in which each beat is subdivided into six parts.Read 1964, 152. In this case, the metre is sometimes characterized as "triple sextuple time". Such a division of time may be encountered more frequently in the Baroque period: for example, variation 26 of the Goldberg Variations by Johann Sebastian Bach has in one hand against in the other, exchanging hands at intervals until the last five bars w ...

Duple And Quadruple Metre
Duple metre (or Am. duple meter, also known as duple time) is a musical metre characterized by a ''primary'' division of 2 beats to the bar, usually indicated by 2 and multiples (simple) or 6 and multiples (compound) in the upper figure of the time signature, with (cut time), , and (at a fast tempo) being the most common examples. Shown below are a simple and a compound duple drum pattern. : \new Staff : \new Staff Though it must, the upper figure being divisible by 2 does not of itself indicate duple metre. The most common time signature in rock, blues, country, funk, and pop is .Schroedl, Scott (2001). ''Play Drums Today!'', p. 42. Hal Leonard. . Although jazz writing has become more adventurous since Dave Brubeck's'' Time Out'', the majority of jazz and jazz standards are still in four time. Duple time is common in many styles including the polka, notorious for its obvious "oom-pah" duple feel. Compare to the waltz. Quadruple metre Quadruple metre (also '' ...

Triple Metre
Triple metre (or Am. triple meter, also known as triple time) is a musical metre characterized by a ''primary'' division of 3 beats to the bar, usually indicated by 3 (simple) or 9 (compound) in the upper figure of the time signature, with , , and being the most common examples. The upper figure being divisible by three does not of itself indicate triple metre; for example, a time signature of usually indicates compound duple metre, and similarly usually indicates compound quadruple metre. Shown below are a simple and a compound triple drum pattern. \new Staff \new Staff Stylistic differences In popular music, the metre is most often quadruple,Schroedl, Scott (2001).

Metre (poetry)
In poetry, metre ( Commonwealth spelling) or meter ( American spelling; see spelling differences) is the basic rhythmic structure of a verse or lines in verse. Many traditional verse forms prescribe a specific verse metre, or a certain set of metres alternating in a particular order. The study and the actual use of metres and forms of versification are both known as prosody. (Within linguistics, " prosody" is used in a more general sense that includes not only poetic metre but also the rhythmic aspects of prose, whether formal or informal, that vary from language to language, and sometimes between poetic traditions.) Characteristics An assortment of features can be identified when classifying poetry and its metre. Qualitative versus quantitative metre The metre of most poetry of the Western world and elsewhere is based on patterns of syllables of particular types. The familiar type of metre in English-language poetry is called qualitative metre, with stressed syllables comin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metre (hymn)
A hymn metre (''US:'' meter) indicates the number of syllables for the lines in each stanza of a hymn. This provides a means of marrying the hymn's text with an appropriate hymn tune for singing. Hymn and poetic metre In the English language poetic metres and hymn metres have different starting points but there is nevertheless much overlap. The hymn ''Amazing Grace'' is used as an example: :Amazing grace, how sweet the sound :that saved a wretch like me. :I once was lost, but now am found, :was blind, but now I see. Analyzing this, a poet would see couplets with four iambic metrical feet in the first and third lines, and three in the second and fourth. A musician would more likely count eight syllables in the first line and six in the second. This would be described as 8.6.8.6 (or 86.86). The words of ''Amazing Grace'' can therefore be set to any tune that has the 8.6.8.6 metre, for example ''The House of the Rising Sun''. Conventionally most hymns in this 86.86 pattern are iam ...

Composite Rhythm
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. 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 over time, of the steps of a dance, or the meter of spoken language and poetry. In some performing arts, such as hip hop music, the rhythmic delivery of the lyrics is one of the most important elements of the style. Rhythm may also refer to visual presentation, as "timed mov ...

Nonsynchronous
Synchronization is the coordination of events to operate a system in unison. For example, the conductor of an orchestra keeps the orchestra synchronized or ''in time''. Systems that operate with all parts in synchrony are said to be synchronous or ''in sync''—and those that are not are ''asynchronous''. Today, time synchronization can occur between systems around the world through satellite navigation signals and other time and frequency transfer techniques. Navigation and railways Time-keeping and synchronization of clocks is a critical problem in long-distance ocean navigation. Before radio navigation and satellite-based navigation, navigators required accurate time in conjunction with astronomical observations to determine how far east or west their vessel traveled. The invention of an accurate marine chronometer revolutionized marine navigation. By the end of the 19th century, important ports provided time signals in the form of a signal gun, flag, or dropping time ...
