Kolmisointu

Kolmisointu is a Finnish term that translates to "chord of three notes" or "triad" in English, referring to a fundamental harmonic building block in Western music theory. It typically consists of three distinct pitches played simultaneously. The most common type of kolmisointu is the triad, which is formed by a root note, a third above the root, and a fifth above the root. The specific quality of the triad – whether it is major, minor, augmented, or diminished – is determined by the intervals between these notes. For instance, a major triad consists of a major third and a perfect fifth above the root, while a minor triad has a minor third and a perfect fifth. These basic three-note structures are the foundation for much of the harmony found in popular music, classical compositions, and various other musical genres. Understanding the construction and function of a kolmisointu is essential for anyone studying music theory or learning to play a musical instrument. They form the basis of chords and are used to create harmonic progressions and add color and depth to melodies.
