the main defect of' dobereiner's triads is that he put the chemically dissimilar elements in the same triads (dahal.ramchandra@gmail.com)
No, Dobereiner's triads were a set of three elements with similar properties where the atomic mass of the middle element was approximately the average of the other two. Newlands' Octaves, on the other hand, arranged elements in rows of seven, where every eighth element showed similar properties. These two classification schemes were different from each other.
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.
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).
Dobereiner was responsible for grouping element into triads. He grouped 3 element with same properties together.
When two triads are played at the exact same time, it is commonly called a Polychord. Poly typically means three.

Some scientists supported Johann Dobereiner's theory of triads, which suggested that certain elements had similar properties and could be grouped together. However, the theory was later replaced by the modern periodic table developed by Dmitri Mendeleev.
Döbereiner's triads were rejected because they did not work for all elements and their properties as more elements were discovered. They were limited to grouping only a few elements with similar properties, and the periodic table provided a more comprehensive and accurate organization of elements based on atomic number and properties.
Dobereiner's classification, which grouped elements into triads based on similar properties, had several limitations. It only encompassed a small number of elements, primarily focusing on the known elements at the time, which were insufficient to represent the entire periodic table. Additionally, not all elements could be neatly categorized into triads, and it failed to account for the periodicity of properties across larger groups of elements. This classification system was ultimately superseded by more comprehensive frameworks, like Mendeleev's periodic table.
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.
a note
A classical accompaniment style based on triads.
Johann Wolfgang Dobereiner,a German chemist arranged atom in the form of triads in 1817.
The major triads are typically named based on their root notes, which include C major, D major, E major, F major, G major, A major, and B major. Each triad consists of three notes: the root, the major third, and the perfect fifth. In addition to these, there are minor triads, diminished triads, and augmented triads, which also have their own names based on the root notes.
