Music: Triads
WHAT IS THE QUALITY OF THE TRIAL IF THE INTERVAL BETWEEN THE ROOT AND THIRD IS M3 AND THE INTERVAL BETWEEN THE THIRD AND FIFTH IS M3?
1. major
2. minor
3. augmented
4. diminished
The quality of the triad if the interval between the root and third is M3 and the interval between the third and fifth is M3 is:
1. Major
The quality of the triad with a major third (M3) interval between the root and third and a minor third (m3) interval between the third and fifth is:
Answer 1: major
To determine the quality of a triad, we need to look at the intervals between the root, third, and fifth. Let's break down the given intervals:
"M3" refers to a major third, which is made up of 4 half steps.
"M3" refers to another major third, which is again made up of 4 half steps.
Now, adding these intervals together, we have a total of 8 half steps for the distance between the root and the fifth.
In a major triad, the interval between the root and the fifth is a perfect fifth, which consists of 7 half steps. However, in this case, we have 8 half steps. This means the interval between the root and the fifth is larger than a perfect fifth.
When the interval between the root and the fifth is larger than a perfect fifth, we call it "augmented." Therefore, the quality of the triad with a M3 interval between the root and third, and another M3 between the third and fifth is "3. augmented."
