What is the quali8ty of the triad if the interval between the root and third is m3 and the interval between the third and fifth is m3?

Answer 1

If the interval between the root and third is a minor third (m3) and the interval between the third and fifth is also a minor third (m3), then the triad will be a diminished triad.

A diminished triad consists of two minor thirds stacked on top of each other. It is characterized by a root, a minor third above the root, and then another minor third above that note. The quality of the triad is described as "diminished" due to the presence of these two minor thirds.
