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?
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.
The quality of the triad can be determined based on the given intervals.
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), the triad is classified as a diminished triad.
To determine the quality of a triad based on the interval between the root, third, and fifth, we need to examine the number of semitones in each interval. In this case, 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).
A minor third consists of three semitones. Therefore, we can count the semitones to find the notes involved and identify the quality of the triad. Let's start from the root note:
1. From the root, count up three semitones to reach the third.
2. From the third, count up three semitones to reach the fifth.
If we perform this counting starting from any root note, we would find that the resulting triad has a root, a minor third, and a minor fifth. Therefore, this triad is classified as a diminished triad.
In summary, the quality of the triad, given a minor third interval between the root and third, and a minor third interval between the third and fifth, will always be a diminished triad.
