sointuviin

Sointuviin is a term that appears in some Finnish-language discussions of music theory to describe the tendency of a passage, piece, or composer to steer harmony toward particular sonorities or chord colors. The word combines sointu (“chord; harmony”) with the suffix -viin, which in Finnish can indicate direction or relation toward something.

The term is not part of the standard Finnish musical lexicon and has no official definition in major dictionaries. In practice, sointuviin is a descriptive label used by some writers to talk about harmonic coloration, modulation tendencies, or the way a melody interacts with chord progressions to create a sense of tonal direction. Because of its informal status, its meaning can vary between texts.

In usage, sointuviin may be employed to discuss topics such as harmonic color, chromatic voice-leading, and the way a composition emphasizes certain chord families or tones. It is related to broader concepts such as sointu, harmonia, modulaatio, and tonality. The term tends to appear in analytical or pedagogical contexts rather than as a standard category in music theory.
