Final answer:
Without hearing the excerpt, it is not possible to categorically determine the vocal style described.
Step-by-step explanation:
The vocal style described in the excerpt could be one of several options based on different characteristics of singing. Without having the excerpt for reference, we cannot definitively determine which vocal style is being described. However, we can define each of the given terms:
Bel canto refers to a vocal style that emphasizes the beauty of sound and the virtuosity of vocal technique. It is closely associated with Italian opera from the early 19th century.
Sprechstimme is a vocal style that combines elements of singing and speaking. It was developed by composer Arnold Schoenberg and is often used in expressionist music.
Coloratura is a style that refers to elaborate ornamentation and agility in singing, often involving fast scales and high notes.
Legato is a term used to describe a smooth, flowing manner of singing or playing, where notes are connected smoothly without any noticeable breaks.
To categorize the vocal style heard in an excerpt, one must listen to the performance and identify the characteristics that align with one of these terms.
