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").

Time Signature
The time signature (also known as meter signature, metre signature, or measure signature) is a notational convention used in Western culture, Western musical notation to specify how many beat (music), beats (pulses) are contained in each measure (bar (music), bar), and which note value is equivalent to a beat. In a music score, the time signature appears at the beginning as a time symbol or stacked numerals, such as or (read ''common time'' or ''four-four time'', respectively), immediately following the key signature (or immediately following the clef symbol if the key signature is empty). A mid-score time signature, usually immediately following a barline, indicates a change of meter (music), meter. There are various types of time signatures, depending on whether the music follows regular (or symmetrical) beat patterns, including Time signature#Simple, simple (e.g., and ), and Time signature#Compound, compound (e.g., and ); or involves shifting beat patterns, including #C ...

Counting (music)
In music, counting is a system of regularly occurring sounds that serve to assist with the performance or audition of music by allowing the easy identification of the beat. Commonly, this involves verbally counting the beats in each measure as they occur, whether there be 2 beats, 3 beats, 4 beats, or even 5 beats. In addition to helping to normalize the time taken up by each beat, counting allows easier identification of the beats that are stressed. Counting is most commonly used with rhythm (often to decipher a difficult rhythm) and form and often involves subdivision. Introduction to systems: numbers and syllables The method involving numbers may be termed ''count chant'', "to identify it as a unique instructional process." In lieu of simply counting the beats of a measure, other systems can be used which may be more appropriate to the particular piece of music. Depending on the tempo, the divisions of a beat may be vocalized as well (for slower times), or skipping numbers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyrhythm
Polyrhythm is the simultaneous use of two or more rhythms that are not readily perceived as deriving from one another, or as simple manifestations of the same meter. The rhythmic layers may be the basis of an entire piece of music ( cross-rhythm), or a momentary section. Polyrhythms can be distinguished from irrational rhythms, which can occur within the context of a single part; polyrhythms require at least two rhythms to be played concurrently, one of which is typically an irrational rhythm. Concurrently in this context means within the same rhythmic cycle. The underlying pulse, whether explicit or implicit can be considered one of the concurrent rhythms. For example, the son clave is poly-rhythmic because its 3 section suggests a different meter from the pulse of the entire pattern. In western art music In some European art music, polyrhythm periodically contradicts the prevailing meter. For example, in Mozart's opera '' Don Giovanni'', two orchestras are heard playing ...

Note Value
In music notation, a note value indicates the relative duration of a note, using the texture or shape of the '' notehead'', the presence or absence of a ''stem'', and the presence or absence of ''flags/ beams/hooks/tails''. Unmodified note values are fractional powers of two, for example one, one-half, one fourth, etc. A rest indicates a silence of an equivalent duration. List Shorter notes can be created theoretically ''ad infinitum'' by adding further flags, but are very rare. Variations The breve appears in several different versions, as shown at right. The first two are commonly used; the third is a stylistic alternative. Sometimes the longa or breve is used to indicate a very long note of indefinite duration, as at the end of a piece (e.g. at the end of Mozart's Mass KV 192). A single eighth note, or any faster note, is always stemmed with flags, while two or more are usually beamed in groups.Gerou, Tom (1996). ''Essential Dictionary of Music Notation'', p.211. Alfr ...

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. Pitch may even be considered a part of duration. 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 descr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Beat (music)
In music and music theory, the beat is the basic unit of time, the pulse (regularly repeating event), of the ''mensural level'' (or ''beat level''). The beat is often defined as the rhythm listeners would tap their toes to when listening to a piece of music, or the numbers a musician counts while performing, though in practice this may be technically incorrect (often the first multiple level). In popular use, ''beat'' can refer to a variety of related concepts, including pulse, tempo, meter, specific rhythms, and groove. Rhythm in music is characterized by a repeating sequence of stressed and unstressed beats (often called "strong" and "weak") and divided into bars organized by time signature and tempo indications. Beats are related to and distinguished from pulse, rhythm (grouping), and meter: Metric levels faster than the beat level are division levels, and slower levels are multiple levels. Beat has always been an important part of music. Some music genres su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tuple
In mathematics, a tuple is a finite ordered list (sequence) of elements. An -tuple is a sequence (or ordered list) of elements, where is a non-negative integer. There is only one 0-tuple, referred to as ''the empty tuple''. An -tuple is defined inductively using the construction of an ordered pair. Mathematicians usually write tuples by listing the elements within parentheses "" and separated by a comma and a space; for example, denotes a 5-tuple. Sometimes other symbols are used to surround the elements, such as square brackets " nbsp; or angle brackets "⟨ ⟩". Braces "" are used to specify arrays in some programming languages but not in mathematical expressions, as they are the standard notation for sets. The term ''tuple'' can often occur when discussing other mathematical objects, such as vectors. In computer science, tuples come in many forms. Most typed functional programming languages implement tuples directly as product types, tightly associated with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beam (music)
In musical notation, a beam is a horizontal or diagonal line used to connect multiple consecutive notes (and occasionally rests) to indicate rhythmic grouping. Only eighth notes (quavers) or shorter can be beamed. The number of beams is equal to the number of flags that would be present on an unbeamed note. ''Beaming'' refers to the conventions and use of beams. A primary beam connects a note group unbroken, while a secondary beam is interrupted or partially broken. Grouping Beam spans indicate rhythmic groupings, usually determined by the time signature. Therefore, beams do not usually cross bar lines or major subdivisions of bars. A single eighth note, or any faster note, is always stemmed with flags, while two or more are typically beamed in groups. In modern practice, beams may span across rests in order to make rhythmic groups clearer. In vocal music, beams were traditionally used only to connect notes sung to the same syllable. In modern practice it is more common to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
