What does it mean when a melody has an arch contour?

• A. It stays flat
• B. It descends at the beginning, reaches a low point, then ascends toward the end
• C. It descends then ascends
• D. It ascends at the beginning, reaches a climatic high point, then descends toward the end

Answer: (D)

An arch contour means the melody rises from the start to a high point and then falls toward the end. It climbs to a climactic moment, then moves downward as the line approaches the close, like the shape of an arch. This simple rise-then-fall pattern creates a sense of lift followed by resolution. The other shapes—staying flat, dipping and then rising, or descending and then ascending—describe different melodic curves that don’t match the arch.
