ENharmonisoidut

ENharmonisoidut is a Finnish term used in music theory to describe pitches, chords, or passages that have been enharmonically respelled to fit a particular harmonic or notational context. Enharmonic respelling means assigning a different spelling to the same pitch class without altering its sounding pitch in equal-tempered tuning. The term is the plural and past participle form of enharmonisoida, and it is commonly used in analyses and discussions of harmony and modulation in Finnish-language sources.

In practice, enharmonisoidut factors arise when writers or composers want to reflect a chord function, key signature, or modulation more clearly. For example, a note that could be written as C sharp or D flat may be respelled as one or the other to align with the surrounding harmony or to facilitate smooth voice leading. Similarly, an interval or chord might be notated in an enharmonically respelled form to emphasize its role in a given key or tonal center. Such respellings do not change the actual pitch in equal temperament, but they do change its theoretical name and its relationship to other notes.

Contextual considerations include tuning systems different from equal temperament, where enharmonic spellings can have different practical consequences, and classical harmony practices where diminished seventh chords or chromatic modulations rely on specific spellings to indicate target keys. ENharmonisoidut thus concerns how notation and analysis reflect harmonic function, not just sound.
