This provides a visualization of the principle of parsimonious voice-leading, in which motions between chords are considered smoother when fewer pitches change. This principle is especially important in analyzing the music of late-19th century composers like Wagner, who frequently avoided traditional tonal relationships.
The illustration highlights the concept of smooth chord progressions, where transitions between chords are more efficient when fewer pitches change. This principle is especially important in understanding the music of late-19th century composers such as Wagner, who frequently pushed the boundaries of traditional harmony and tonality.
