atonality

The word 'atonality' is a modern musical term constructed from classical components. Its core is the Greek root 'tonos,' which originally meant "a stretching, tension, or pitch," and evolved in Latin and Romance languages to denote musical tone. This is prefixed with the Greek negative 'a-,' meaning "without," to directly negate the concept of tone in its traditional sense. The suffix '-ality,' a Latinate compound, is then added to form an abstract noun describing the quality or state of being without tonal center. Thus, the term's literal construction—"the state of being without tone"—logically encapsulates the 20th-century compositional departure from established harmonic systems, where 'tone' specifically refers to a hierarchical key center.
