The Vietnamese word "nữ trầm" refers to a specific vocal range in music, which is known in English as "contralto." This term is used to describe a female singer with a deep, rich voice that typically sings in the lower range.
In a more advanced context, you might discuss the qualities and techniques of a "nữ trầm," such as their ability to perform in lower registers, their unique timbre, and how they contribute to the overall harmony in choral music.
There aren't many direct variants of "nữ trầm," but you can encounter related terms like: - Nam trầm: This refers to a male singer with a deep voice, known as a "bass." - Nữ cao: This is the term for a female singer with a higher vocal range, known as a "soprano."
While "nữ trầm" primarily pertains to vocal classification, it can also be used metaphorically to describe something deep or profound in a non-musical context, but this usage is less common.
