Which of the following are the three primary chord types?

The three primary chord types consist of major, minor, and diminished chords. Major chords are built with a root, a major third, and a perfect fifth, creating a bright and happy sound. Minor chords also have a root and a perfect fifth but are built with a minor third instead, resulting in a darker, more melancholic sound. Diminished chords are formed with a root, a minor third, and a diminished fifth, producing a tense and unstable quality.

Understanding these three types is fundamental in music composition and analysis, as they form the basis for many harmonic progressions and help define the emotional character of a piece. Each chord type conveys different feelings and functions within a musical context, which is essential for any musician or student of music theory.
