diatonic means relating to or characteristic of a musical scale which contains seven pitches and a pattern of five whole tones and two semitones; particularly, of the major or natural minor scales.
diatonic is pronounced /ˌdaɪəˈtɒnɪk/.
Why “diatonic” is a great word
Relating to a musical scale of seven pitches arranged in a pattern of five whole tones and two semitones per octave, as in the major or natural minor. From Late Latin *diatonicus*, from Ancient Greek διατονικός (*diatonikós*), from διάτονος (*diátonos*), likely meaning 'stretched through' or 'progressing through tones' (from διά (*diá*, 'through') + τόνος (*tónos*, 'tone, tension')). Unlike "chromatic," which floods the ear with all twelve semitones, or "enharmonic," which dwells in the notational shadows of a single pitch, diatonic is the architecture of a key, a bounded field where seven notes establish gravity and return. It is the white keys of a piano catching morning light, the breath-like rise of a folk melody, and the open, sunlit road of a melody that feels like home—the foundational geometry of Western harmony, worn smooth by the weight of songs unsung but somehow always known.
Etymology
From French diatonique or Late Latin diatonicus, ultimately from Ancient Greek διατονικός (diatonikós), in the phrase [γένος (génos, “type, genus”)] διατονικός (diatonikós) (in reference to the diatonic tetrachord, and in contrast to the chromatic and enharmonic tetrachords), from διάτονος (diátonos) (διά (diá) + τόνος (tónos)), of disputed etymology, as both components are ambiguous.
Most plausibly, διάτονος (diátonos) refers to “stretched intervals”, as the intervals of the diatonic tetrachord are the most evenly distributed or “stretched out”, compared to the chromatic and enharmonic tetrads, which use smaller, more crowded together intervals. Compare pyknon, from πυκνός (puknós, “dense, compressed”), referring to the lower part of the non-diatonic tetrachords: the diatonic tetrachord h
