Diatonic

In music, 'diatonic' refers to a scale or melody that uses only the notes belonging to a specific key, without any accidentals (sharps or flats) that aren't part of that key's natural collection. A diatonic scale, therefore, comprises seven notes within an octave, each a whole step or half step away from its neighbors. This stands in contrast to chromatic music, which uses all twelve notes within an octave. diatonic music emphasizes a clear tonal center and generally avoids complex harmonic structures, creating a sense of simplicity and stability. This fundamental structure is pivotal for understanding Western music theory and harmony.

Diatonic meaning with examples
