trichordian

Trichordian refers to a musical concept where a chord is composed of three notes. The term is derived from the Greek words "tri," meaning three, and "chord," referring to a harmony of notes. Trichordian chords are fundamental to Western music theory, as they form the basis for many common chords, such as major, minor, and diminished triads. These chords are typically built using intervals of a third and a fifth above a root note. For example, a C major trichord consists of the notes C, E, and G. The trichordian structure is essential in various musical genres and styles, providing a foundation for harmony and melody. The simplicity and versatility of trichordian chords make them a cornerstone of musical composition and analysis.
