Triadic is a term commonly used in music theory to describe a chord or harmonization that consists of three distinct notes. However, there are several alternative words that can be used to describe this concept. One synonym is "triadic harmony," which refers to the use of triads in music composition. Other synonyms include "three-note chord," "three-part harmony," and "trichord." These terms are all used to describe the same concept of using three distinct notes to create a chord or harmonization, and are often used interchangeably in music theory and composition. Whether you prefer to use "triadic" or one of its synonyms, the concept remains the same - a three-note chord that creates a pleasing musical sound.
