Examples

  • First, we'll understand why any quadruplet of four points that form the vertices of square always give you the same pitch, common pitch.

  • Instead, they seem to contain all six points with two 2s, and perhaps half of the 12 points with one 2 and at most 2 of the 8 points with no 2s (because we can divide these 8 points into two quadruplets ***=111,133,313,331 and ***=333,311,131,113, each of which can have at most one point), leading to as many as 14 points, which is not quite good enough.

Morphology

quadruplet = quadruple (semi-transparent) = quadruple + et

The connection to 'quadruple' is clear, but the noun form is a conventional lexical item rather than a fully regular meaning extension.

Etymology

The word quadruplet comes from the part quadru- meaning 'four' and the small-group ending -plet, the same idea you see in triplet. So a quadruplet is simply a set of four similar things counted as one group.
