What type of dramatic work is characterized by music and can feature singers and instrumentalists?

The type of dramatic work characterized by music and that can feature both singers and instrumentalists is an opera. Opera combines a narrative with music as a central component, often incorporating orchestras and a variety of vocal styles. The emphasis on the integration of music into storytelling is fundamental to opera, distinguishing it from other forms of theatrical productions.

While musicals share some similarities, as they also include music and singing, they often contain spoken dialogue and may feature more diverse styles of music beyond the more classical elements typically associated with opera. Thus, the essence of opera lies in its dedication to music as the primary vehicle for storytelling, with no dialogue spoken.

Dance Theatre, on the other hand, primarily focuses on movement and choreography, often with minimal text, and typically does not have the same emphasis on vocal performance combined with instrumental music. Spoken Word focuses on the poetic recitation of text and does not inherently involve music or musical accompaniment. Therefore, considering these defining characteristics allows us to confidently identify opera as the correct answer.
