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.)" (Humphries 2002, 266). 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 is the "triplet".

Terminology

The modern term 'tuplet' comes from a mistaken splitting of the suffixes of 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, suffix¹"). An alternative modern term, "irrational rhythm", was originally borrowed from Greek prosody where it referred to "a syllable having a metrical value not corresponding to its actual time-value, or ... a metrical foot containing such a syllable" (Oxford English Dictionary, entry "irrational"). The term would be incorrect if used in the mathematical sense (because the note-values are rational fractions) or in the more general sense of "unreasonable, utterly illogical, absurd".

Triplet state

In quantum mechanics, a triplet is a quantum state of a system with a spin of 1, such that there are three allowed values of the spin component: −1, 0 and +1.

Spin, in the context of quantum mechanics, is not a mechanical rotation but a more abstract concept that characterizes a particle's intrinsic angular momentum. It is particularly important for systems at atomic length scales, such as individual atoms, protons, or electrons.

Almost all molecules encountered in daily life exist in a singlet state, but molecular oxygen is an exception. At room temperature, O₂ exists in a triplet state, which can only undergo a chemical reaction by making the forbidden transition into a singlet state. This makes it kinetically nonreactive despite being thermodynamically a strong oxidant. Photochemical or thermal activation can bring it into the singlet state, which makes it kinetically as well as thermodynamically a strong oxidant.

Two spin-1/2 particles

In a system with two spin-1/2 particles - for example the proton and electron in the ground state of hydrogen, measured on a given axis, each particle can be either spin up or spin down so the system has four basis states in all

New (album)

New (stylised as III☰III) is the sixteenth studio album by Paul McCartney, released on 14 October 2013 in the United Kingdom and the following day in the United States. The album was his first since 2007's Memory Almost Full to consist entirely of new compositions.

The album was executive produced by Giles Martin, with production by Martin, Mark Ronson, Ethan Johns and Paul Epworth and it was mastered by Ted Jensen at Sterling Sound, New York. McCartney has stated that New was inspired by recent events in his life as well as memories of his pre-Beatles history. He added that some of the arrangements are unlike his usual rock recordings, and that he specifically sought out younger producers to work with. He and his stage band performed in various venues to promote the album, along with promotional events held through social media.

The first single, "New", and the album were met with a generally favourable reception from music critics. The album peaked at number 3 on the UK Albums Chart and on the US Billboard 200.
