Tonaliikkaa

Tonaliikkaa is a Finnish word that translates to "tonality" in English. It refers to the system of organizing musical pitches into a hierarchy of stability and tension, which is fundamental to Western music theory. The concept of tonaliikkaa is closely tied to the use of scales and chords, particularly the major and minor scales, which form the basis of tonal music.

In tonaliikkaa, certain pitches are considered more stable than others. For example, in the key of C major, the tonic (C) and the dominant (G) are the most stable pitches, while the subdominant (F) and the mediant (E) are less stable. This hierarchy of stability is reflected in the use of chords, with the tonic chord (C major) and the dominant chord (G major) being the most stable, and the subdominant chord (F major) and the mediant chord (E minor) being less stable.

Tonaliikkaa also involves the use of modulation, which is the process of changing from one key to another. Modulation can be achieved through various techniques, such as the use of dominant chords, the use of secondary dominants, and the use of chromatic alteration.

The concept of tonaliikkaa has been a subject of debate among music theorists, with some arguing that it is a necessary feature of Western music, while others argue that it is a historical artifact that has outlived its usefulness. Despite these debates, tonaliikkaa remains a central concept in the study of Western music theory.
