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.
Tuplet A tuplet is a group of notes that would not normally fit into the rhythmic space they occupy. The example shown is a quarter-note triplet—three quarter notes are to be played in the space that would normally contain two. (To determine how many "normal" notes are being replaced by the tuplet, it is sometimes necessary to examine the ...

The short–long notes inégales, or "scotch snap" can be found to be nearly begging for use at the ends of certain phrases, typically in a triplet based texture, and for instance especially in a Menuet that features triplets, where often at the cadential points, the triplets fall away and playing the evenly notated 8th notes seem to invite a ...
Since C = 2πr, the circumference of a unit circle is 2π. In mathematics, a unit circle is a circle of unit radius—that is, a radius of 1. [1] Frequently, especially in trigonometry, the unit circle is the circle of radius 1 centered at the origin (0, 0) in the Cartesian coordinate system in the Euclidean plane.
For the group on the unit circle, the appropriate subgroup is the subgroup of points of the form (w, x, 1, 0), with + =, and its identity element is (1, 0, 1, 0). The unit hyperbola group corresponds to points of form (1, 0, y, z), with =, and the identity is again (1, 0, 1, 0). (Of course, since they are subgroups of the larger group, they ...
Examples of atoms in singlet, doublet, and triplet states. In quantum mechanics, a triplet state, or spin triplet, is the quantum state of an object such as an electron, atom, or molecule, having a quantum spin S = 1. It has three allowed values of the spin's projection along a given axis m S = −1, 0, or +1, giving the name "triplet".
So, the 3 × 3 generators L displayed above act on the triplet (spin 1) representation, while the 2 × 2 generators below, t, act on the doublet representation. By taking Kronecker products of D 1/2 with itself repeatedly, one may construct all higher irreducible representations D j .
