harmoniekspander

Harmoniekspander is a term used in Scandinavian music contexts that can denote several related ideas centered on expanding harmonic content. The lack of a single, standardized definition means it may refer to either a theoretical approach in music composition or an audio processing tool.

In a theoretical sense, harmoniekspander may describe methods for enriching a chord progression by adding extended chords, secondary dominants, modal mixture, chromatic mediants, planing, or other devices that widen harmonic color and functional relationships beyond basic triads.

In audio production, it can refer to a device, plugin, or software feature that generates additional pitches to form harmonies from a given input. Such harmonizers typically perform pitch analysis and create one or more harmony voices at set intervals, with controls for voice leading, formants, and mix level, used to create thick vocal or instrumental textures.

Etymology: The term is a compound of harmoni (harmony) and ekspander (expander). It is not widely used in English-language sources and is most common in Danish-language materials or marketing for music software.

Usage and reception: Because the term lacks a fixed definition, interpretations vary by vendor or author; the concept aligns with broader categories of harmony expansion and pitch-correction/harmonization tools in digital audio workstations.
