To an overview of tonalities belongs also chromaticism. Though not anchored, it is an essential ingredient for musical coloring and for leading to modulations between tonalities.
The chromatic or twelve-tone scale consists of all twelve semitones in an octave. Chromaticism intersperses the pitches of a tonality with other chromatic scale pitches. These contrast and expand a given tonality. They may temporarily indicate or lead to a modulation from one tonality to another. During the last half of the nineteenth century, the concept of tonality expanded with the chromatic scale and chromaticism becoming more widely used, e.g. in Richard Wagner’s “Tristan und Isolde“. This opened up more tonal freedom and relaxation — what some called the breakdown of tonality.
The module Anchored Tonality Modulation Samples is a very practice-oriented adjunct to the catalogue of anchored tonalities and the five-course seriesHarmonic and Tonality Fundamentals. Below are its currently over forty visuals. To facilitate finding smooth modulation paths, this module provides an overview of the tonalities included in the catalogue grouped by tetrachords, both by lower ones and by upper ones. Further, it presents — condensed as well as in detail — examples of cyclic modulation paths, which move through a number of tonalities and eventually return to where they originated from.
