what is the quality of the triad of the bottom third is minor and the top third is major

The quality of a triad is determined by the combination of intervals between its notes. In this case, if the bottom third is minor and the top third is major, we can determine the quality of the triad by following these steps:

1. Understand the structure of a triad: A triad is a three-note chord consisting of a root, a third, and a fifth. The quality of a triad is defined by the type of intervals between these notes.

2. Determine the root note: The root note is the foundation of the triad. It can be any note in music, represented by a letter (A, B, C, etc.).

3. Identify the bottom third: Counting from the root note, find the note that is a third below it. To determine if it's a minor third, you need to understand the pattern of whole steps and half steps. A minor third consists of 1.5 whole steps or three half steps.

4. Identify the top third: Counting from the root note, find the note that is a third above it. To determine if it's a major third, a major third consists of two whole steps or four half steps.

5. Analyze the quality of the triad: After identifying the bottom and top thirds, you can determine the quality of the triad based on the interval between the root note and the notes forming the third above and below it. If the bottom third is minor and the top third is major, it creates a specific type of triad known as a "minor-major triad."

A "minor-major triad" has a root note, a minor third, and a major fifth.

Remember, this explanation assumes that you have knowledge of music theory, including intervals and triads.
