What is a harmonic interval?

• A. When the two pitches occur in succession
• B. The distance between two pitches in different octaves
• C. When the two pitches occur simultaneously
• D. A minor interval

Answer: (C)

A harmonic interval is the distance between two pitches that are heard at the same time. When two notes are sounded together, you hear a single sonority, like a tiny chord, and the interval between those pitches determines the harmony. This is different from a melodic interval, where the same two notes occur one after another rather than simultaneously. The idea of “different octaves” or “minor quality” doesn’t define harmonic versus melodic; those describe other aspects (octave range or size of the interval), but not the basic simultaneity. So the defining feature is that the two pitches occur simultaneously, such as C and E sounding together to form a harmonic interval.
