Definition

Noun: A gapped scale is a musical scale that contains fewer than seven notes within an octave. This distinguishes it from a heptatonic (seven-note) scale, such as the common major or minor scale. The "gaps" refer to the intervals where expected notes are omitted, creating a distinct melodic and harmonic character.

Usage
