Which term describes the change from one tonality (tonic, or tonal center) to another?

• A. Modulation
• B. Tonality
• C. Time signature
• D. Unison

Answer: (A)

Shifting the home pitch from one key to another is modulation. It creates a new tonal center, giving the music a fresh sense of key and a different set of chords that feel at rest. This move can be smooth, using a pivot chord that belongs to both keys, or it can happen abruptly with a direct arrival in the new key. Understanding modulation helps you hear why a section sounds like it’s moved to a new home while the overall structure may still feel connected. Tonality is the broader system of organizing music around a tonic, time signature is about rhythm and meter, and unison is when players sing or play the same pitch. So the term for changing from one tonality to another is modulation.
