mollfunktion

Mollfunktion is a term used in the field of music theory and composition to describe a specific type of chord progression or harmonic structure. The term is derived from the German word "Moll," which means "minor" in English. A mollfunktion chord progression typically involves the use of minor chords, often with a focus on the natural minor scale or its modes. This type of progression is characterized by its melancholic or introspective mood, often used in classical and romantic music.

The concept of mollfunktion was developed by the German composer and theorist Hugo Riemann in the 19th century. Riemann's theory of tonality, known as Riemann's theory, is a foundational work in music theory that explores the relationships between chords and keys. In this context, mollfunktion refers to the use of minor chords in a way that maintains a sense of tonal stability and coherence.

A mollfunktion progression often begins with a minor triad, such as Am or Cm, and then moves to related chords, such as the relative major (C or E) or the parallel major (A or C). The progression may also include the use of secondary dominants, passing chords, or other harmonic devices to create a sense of movement and tension within the minor key.

Mollfunktion is not limited to a specific style or period of music. It can be found in various genres, from classical sonatas to modern jazz compositions. The use of mollfunktion allows composers to explore the expressive potential of minor chords while maintaining a sense of tonal structure and coherence.
