Polychord
When two triads are played at the exact same time, it is commonly called a Polychord. Poly typically means three.

The two most common triads are the Major and the minor triad. The other two types of triads are diminished and augmented triads.
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.

the main defect of' dobereiner's triads is that he put the chemically dissimilar elements in the same triads (dahal.ramchandra@gmail.com)
In music, triads can be identified by looking for three notes played together that create a chord. These notes are usually a root note, a third note, and a fifth note of a scale.
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 law of triads helped in identifying patterns and relationships among elements, leading to the development of the periodic table. It also played a key role in the early classification of elements based on their atomic masses and properties. However, the law of triads was later superseded by more accurate and comprehensive periodic table arrangements.
