Which term means "The sound produced by combining two vowels into a single syllable"?

• A. con spirito
• B. con anima
• C. diphthong
• D. dolce

Answer: (C)

The main concept is diphthong, which is a sound formed when two vowels blend into a single syllable. It starts with one vowel sound and glides into another within that one syllable, like the way “coin” or “loud” feel as a single, smooth syllable rather than two separate ones. In singing, recognizing diphthongs helps keep phrases flowing with clear vowel shapes while staying on one beat. The other terms aren’t about vowel blending; con spirito means with spirit, con anima means with soul, and dolce means sweet—these describe mood or expression, not how vowels combine. So the term that means a sound produced by combining two vowels into one syllable is diphthong.
