Etymology
the word 'harmony' entered english in the late 14th century via old french 'armonie', from latin 'harmonia', which was borrowed from greek 'harmonia'. in greek, it originally meant a 'means of joining' or 'agreement', derived from the verb 'harmozein' meaning 'to fit together, to join'. this greek root is connected to the proto-indo-european root ar-, meaning 'to fit together'. the concept evolved from the literal fitting of physical parts, like in carpentry, to the abstract fitting together of musical sounds and, by extension, to any state of concord and agreement.
Analysis
the word is a simplex loanword from latin via french. it is not productively formed from separable english morphemes.
