Which term refers to the relationship in pitch between two notes?

• A. Interval
• B. Dissonance
• C. Crescendo
• D. Key Signature

Answer: (A)

Two notes’ pitch relationship is called an interval. An interval describes the distance from one pitch to another, counted in scale steps and semitones, and it has names like minor second, major third, perfect fifth, plus qualities such as major, minor, perfect, diminished, or augmented. Understanding intervals helps explain why melodies move in steps or leaps and how chords are built from stacked intervals. The other terms refer to different ideas: dissonance describes the tense or unstable sound between pitches rather than the distance itself; crescendo is a dynamic marking about getting louder; and a key signature indicates which pitches are altered throughout a piece to establish the tonal center, not the specific distance between two notes.
