Hey look, I can use google just like Botten
General exceptions to the octet rule include molecules that have an odd number of electrons and molecules in which one or more atoms possess more or fewer than eight electrons. Molecules with an odd number of electrons are relatively rare in the s and p blocks but rather common among the d- and f-block elements. Compounds with more than an octet of electrons around an atom are called expanded-valence molecules. One model to explain their existence uses one or more d orbitals in bonding in addition to the valence ns and np orbitals. Such species are known for only atoms in period 3 or below, which contain nd subshells in their valence shell. Learning Objective is to assign a Lewis dot symbol to elements not having an octet of electrons in their compounds.

Those compounds are generally referred to as reaction intermediates, i.e. their existence is an intermediate step in a reaction, and are unstable until they find stability in further reactions which do satisfy the octet rule. I.e NO, carbenes, free radicals, methyl radicals etc.
To bring this back to center, sounds outside of the harmonization of octavew are unstable sounds which demonstrate destructive interference, and as such, these disharmonic sounds "React" with other sounds until they find find equilibrium at an octave between them, exactly like Chemistry does.
Funny that....
