What happens if two pitches occur at the same time?

• A. You either get a harmony or a counterpoint
• B. It creates a new scale
• C. It forms a melody
• D. It belongs to the rhythm only

Answer: (A)

When two pitches occur at the same time, you create a vertical sonority—the basic idea of harmony. The two notes form a dyad, and the relationship between them (the interval) is the simplest building block of harmony. If those simultaneous notes come from two separate melodic lines that move against each other, you’re entering counterpoint, where independent lines interact to shape the musical texture. The other options don’t fit because they describe things that aren’t caused by notes sounding together at that moment: a scale is a sequence of pitches over time, not a single moment; a melody is a linear sequence of pitches over time; rhythm concerns the timing and duration of notes rather than the pitch content.
