Päämittakaavaa
Päämittakaavaa, often translated as "main scale" or "primary scale," refers to the principal or dominant scale used in a piece of music. This scale serves as the tonal center or home key around which the composition is built. It establishes the expected set of pitches and their relationships, defining the overall harmonic and melodic character of the work.
The main scale dictates the key signature of a piece, indicating which notes are sharp or flat
