Which chord is formed by a minor triad and a minor seventh?

• A. Minor Seventh
• B. Major Seventh Chord
• C. Dominant Seventh Chord
• D. Half Diminished Seventh Chord

Answer: (A)

A minor triad consists of a root, a minor third, and a perfect fifth. When you add a seventh that is also minor above the root, you get a chord built from the notes 0, 3, 7, and 10 semitones. That combination is called a minor seventh chord. For example, C minor triad is C–E♭–G; adding the minor seventh above C gives B♭, making C–E♭–G–B♭. The other options describe different seventh chords, which differ in the quality of the triad or the seventh.
