the main defect of' dobereiner's triads is that he put the chemically dissimilar elements in the same triads (dahal.ramchandra@gmail.com)
There are four types of triads: major, minor, augmented, and diminished. Major triads consist of a root, major third, and perfect fifth. Minor triads have a root, minor third, and perfect fifth. Augmented triads have a root, major third, and augmented fifth. Diminished triads have a root, minor third, and diminished fifth.
The two most common triads are the Major and the minor triad. The other two types of triads are diminished and augmented triads.

Johann Wolfgang Dobereiner,a German chemist arranged atom in the form of triads in 1817.
A classical accompaniment style based on triads.
Polychord
Johann Dobereiner grouped elements with similar properties into triads. In these triads, he observed that the properties of the middle element were the average of the other two.
Dmitri Mendeleev arranged the elements into triads in the periodic table. Mendeleev noticed that elements with similar properties occurred at regular intervals when arranged by increasing atomic mass.
a three-note chord,
Triads are chords consisting of three notes: the root, the third, and the fifth. They are the fundamental building blocks of harmony in music. Triads can be major (happy-sounding), minor (sad-sounding), diminished (tense-sounding), or augmented (bright-sounding).
Triads were developed by Giovanni Battista Mancini, an Italian singing teacher and voice instructor in the 18th century. Mancini's work in music theory and vocal pedagogy contributed to the understanding and application of triads in Western music.
