Tonality
Tonality is a hierarchical system of musical organization in which pitches and chords relate functionally to a central reference pitch called the tonic, creating a framework of tension and resolution that governs melodic direction and harmonic progression.
Overview
Tonality served as a primary organizational principle of Western art music from roughly 1600 to 1900, structuring forms across diverse vocal and instrumental repertoire. Tonal hierarchies rely on interval relationships associated with the acoustic properties of the overtone series, such as the 3:2 frequency ratio of the fifth, providing a conventional basis for establishing harmonic tension and stability.
Why it matters
The expansion of chromatic harmony and the emergence of non-tonal systems in the late nineteenth and early twentieth centuries altered composition and music theory. Tonal principles nevertheless remain a foundational organizational framework across film scoring, vernacular traditions, and contemporary popular music.
