In a triad, the fifth is the highest note.

In a triad, the fifth is the highest note.

• A. The lowest note in a triad
• B. The middle note
• C. The highest note in a triad
• D. The root note

Answer: (C)

A triad is formed by stacking two thirds on a root note, giving three notes: the root, the third above it, and the fifth above it. In root position, these three notes sit from bottom to top as root, third, fifth, so the fifth ends up as the highest note in the triad. For example, C–E–G in root position places G—the fifth above C—on top. So the statement matches what you get when the triad is voiced in root position: the top note is the fifth. (If you invert the triad, the bass may change and the highest note could be a different member, but in the common root-position configuration the fifth is the highest.)
