What does the term "tenuto" mean in musical practice?

The term "tenuto" in musical practice indicates that a note should be held for its full value or slightly longer than its written duration. This term is often represented by a horizontal line placed above or below the note. When a musician sees tenuto markings, they understand that they need to give those notes a sense of emphasis, ensuring sustained sound that adds richness and depth to the performance. This practice enhances musical expression, particularly in choral settings where sustaining certain notes can contribute to the overall harmonic structure and emotional impact of the piece being performed.

In contrast, the other options do not accurately reflect the meaning of "tenuto." Breathing at different times relates to phrasing and diction within choral performance but does not connect to the direct interpretation of note duration. Playing loudly pertains to dynamics indicated by terms like "forte," while writing music for a choir involves composition skills rather than performance practice. Therefore, holding a note for its full value or slightly longer encapsulates the essence of the term "tenuto" in musical terminology.
