diminished triads contain two minor thirds stacked, e.g., B–D–F (B diminished).minor triads contain a minor third with a major third stacked above it, e.g., in the minor triad A–C–E (A minor), A–C is a minor third and C–E is a major third.major triads contain a major third with a minor third stacked above it, e.g., in the major triad C–E–G (C major), the interval C–E is major third and E–G is a minor third.Since triads are constructed of stacked thirds, they can be alternatively defined as follows: The above definitions spell out the interval of each note above the root. augmented triads contain a major third, and augmented fifth, symbolized: R 3 ♯5 (or 0–4–8) play ( help.diminished triads contain a minor third, and diminished fifth, symbolized: R ♭3 ♭5 (or 0–3–6) play ( help.minor triads contain a minor third, and perfect fifth, symbolized: R ♭3 5 (or 0–3–7) play ( help.major triads contain a major third and perfect fifth interval, symbolized: R 3 5 (or 0–4–7 as semitones) play ( help.While the interval from each note to the one above it is a third, the quality of those thirds varies depending on the quality of the triad: This spells a triad by skipping over D and F. For example, a C major triad uses the notes C–E–G. Triads (or any other tertian chords) are built by superimposing every other note of a diatonic scale (e.g., standard major or minor scale). The primacy of the triad in Western music was first theorized by Gioseffo Zarlino (1500s), and the term "harmonic triad" was coined by Johannes Lippius in his Synopsis musicae novae (1612). The progression approach, which was the foundation of the Baroque-era basso continuo accompaniment, required a more "vertical" approach, thus relying more heavily on the triad as the basic building block of functional harmony. In the late Renaissance music era, and especially during the Baroque music era (1600–1750), Western art music shifted from a more "horizontal" contrapuntal approach (in which multiple, independent melody lines were interwoven) toward progressions, which are sequences of triads. When we consider musical works we find that the triad is ever-present and that the interpolated dissonances have no other purpose than to effect the continuous variation of the triad. In popular music and 18th-century classical music, major and minor triads are considered consonant and stable, and diminished and augmented triads are considered dissonant and unstable. Three of these four kinds of triads are found in the major (or diatonic) scale. That is, a song or other vocal or instrumental piece can be in the key of C major or A minor, but a song or some other piece cannot be in the key of B diminished or F augmented (although songs or other pieces might include these triads within the triad progression, typically in a temporary, passing role). In standard tonal music, only major and minor triads can be used as a tonic in a song or some other piece of music. Major and minor triads are the most commonly used triad qualities in Western classical, popular and traditional music. Secondarily, a triad's function is determined by its quality: major, minor, diminished or augmented. The root of a triad, together with the degree of the scale to which it corresponds, primarily determine its function. Others use the term to refer to combinations apparently stacked by other intervals, as in " quartal triad" a combination stacked in thirds is then called a " tertian triad". Schillinger defined triads as "A structure in harmony of but three parts conventionally, but not necessarily, the familiar triad of ordinary diatonic harmony." The word used by other theorists for this more general concept is " trichord". Some 20th-century theorists, notably Howard Hanson, Carlton Gamer, and Joseph Schillinger expand the term to refer to any combination of three different pitches, regardless of the intervals. Perfect fifths are the most commonly used interval above the root in Western classical, popular and traditional music.
