Dance Notes

The reels 9-16, and 24-32 have also been called "covalent" reels.
First covalent reel: the change-over couple, instead of passing left shoulder (bar 2) cross up to second place while the down-dancing couple ends (bar 2) in third place.
Second covalent reel: the top person ladies' side and bottom person men's side turn RH (bar 2) to change reels and directions.

Dance Information

The deviser named this strathspey Covalence after his "covalent" reels, as the reels seemed analogous to chemical covalence.

A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms.

These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

The term covalence in regard to bonding was first used in 1919 by Irving Langmuir in a Journal of the American Chemical Society article entitled "The Arrangement of Electrons in Atoms and Molecules". Langmuir wrote that "we shall denote by the term covalence the number of pairs of electrons that a given atom shares with its neighbors.
