What factors most strongly suggests that this piece is an example of secular music?

Secular music is typically characterized by themes that focus on human experiences, emotions, and everyday life rather than religious or spiritual subject matter. If the piece features lyrics that explore love, nature, or social issues, and employs a style that emphasizes rhythm and melody over liturgical elements, it likely indicates a secular nature. Additionally, the absence of traditional religious instruments or motifs further supports this classification. Overall, the focus on personal or worldly themes rather than spiritual ones is a strong indicator of secular music.
