tonusunda

Tonusunda is a term used in music theory to describe a particular relationship between musical pitches. It refers to the concept of a tonal center, or tonic, which acts as a point of rest and resolution within a musical composition or passage. When music is in "tonusunda," it means that the notes and harmonies are organized around and tend to return to this central pitch. This organization creates a sense of key and expectation for the listener.

The tonic is typically the first note of a scale and is often the note on which a piece begins and ends. The feeling of being "in tonusunda" is established through the use of specific chord progressions and melodic patterns that emphasize this tonic. For example, the dominant chord, which is built on the fifth scale degree, has a strong tendency to resolve to the tonic chord, reinforcing the sense of tonality.

Understanding "tonusunda" is fundamental to comprehending Western tonal music. It explains why certain melodies feel complete and resolved, and how composers create tension and release through their manipulation of pitches and harmonies. While modern music has explored various systems that depart from traditional tonality, the concept of a tonal center remains a significant element in the analysis and creation of much of the music we hear.
