  2. Counting (music) - Wikipedia

    en.wikipedia.org/wiki/Counting_(music)

    Quarter note triplets, due to their different rhythmic feel, may be articulated differently as "1 dra git 3 dra git". [3] Rather than numbers or nonsense syllables, a random word may be assigned to a rhythm to clearly count each beat. An example is with a triplet, so that a triplet subdivision is often counted "tri-pl-et". [4]

  3. Tuplet - Wikipedia

    en.wikipedia.org/wiki/Tuplet

    The most common tuplet [9] is the triplet (German Triole, French triolet, Italian terzina or tripletta, Spanish tresillo).Whereas normally two quarter notes (crotchets) are the same duration as a half note (minim), three triplet quarter notes have that same duration, so the duration of a triplet quarter note is 2 ⁄ 3 the duration of a standard quarter note.

  4. Tresillo (rhythm) - Wikipedia

    en.wikipedia.org/wiki/Tresillo_(rhythm)

    Tresillo is a Spanish word meaning "triplet"—three equal notes within the same time span normally occupied by two notes. In its formal usage, [further explanation needed] tresillo refers to a subdivision of the beat that does not normally occur within the given structure. Therefore, it is indicated by the number 3 between the halves of a ...

  5. Prefix sum - Wikipedia

    en.wikipedia.org/wiki/Prefix_sum

    Prefix sums are trivial to compute in sequential models of computation, by using the formula y i = y i − 1 + x i to compute each output value in sequence order. However, despite their ease of computation, prefix sums are a useful primitive in certain algorithms such as counting sort, [1] [2] and they form the basis of the scan higher-order function in functional programming languages.

  6. Formulas for generating Pythagorean triples - Wikipedia

    en.wikipedia.org/wiki/Formulas_for_generating...

    With a the shorter and b the longer legs of a triangle and c its hypotenuse, the Pythagoras family of triplets is defined by c − b = 1, the Plato family by c − b = 2, and the Fermat family by | a − b | = 1. The Stifel sequence produces all primitive triplets of the Pythagoras family, and the Ozanam sequence produces all primitive triples ...

  7. Counting - Wikipedia

    en.wikipedia.org/wiki/Counting

    Number blocks, which can be used for counting. Counting is the process of determining the number of elements of a finite set of objects; that is, determining the size of a set. . The traditional way of counting consists of continually increasing a (mental or spoken) counter by a unit for every element of the set, in some order, while marking (or displacing) those elements to avoid visiting the ...

  8. 3-partition problem - Wikipedia

    en.wikipedia.org/wiki/3-partition_problem

    The goal is to construct m triplets, each of which contains one element from A, one from B and one from C, such that the sum of each triplet is T. [ 2 ] The 4-partition problem is a variant in which S contains n = 4 m integers, the sum of all integers is ⁠ m T {\displaystyle mT} ⁠ , and the goal is to partition it into m quadruplets, all ...

  9. Chinese musical notation - Wikipedia

    en.wikipedia.org/wiki/Chinese_musical_notation

    The table above shows how the numbers represent the note respectively. The Jianpu uses dots above or below the number to show its octave. They also represent the number of octaves. For example, a dot below the number "6" is an octave lower than "6". It also uses dashes (–) to represent the note length.
