nimellisasteikko
Nimellisasteikko is a musical term referring to a scale where the intervals are not derived from a tonal center in the traditional sense, but rather from a series of specific, often chromatic, relationships. Unlike diatonic scales, which have a clear tonic and a defined structure of whole and half steps, nimellisasteikko scales are built using a more arbitrary or programmatic arrangement of intervals. This can lead to scales with unusual intervallic content and a less predictable tonal character.
The term "nimellisasteikko" is not a standard or widely recognized musical term in English-language music theory.
