Which type of drama includes both speech and music?

The choice of musical as the type of drama that includes both speech and music is accurate because musicals are specifically designed to integrate songs, music, and dialogue to advance the plot and develop characters. In a musical, the spoken dialogue is intertwined with musical numbers, allowing for emotional expression and storytelling through both mediums.

In contrast, opera is a form of theatre in which the musical elements dominate, often featuring little to no spoken dialogue; it is primarily sung throughout. While drama generally refers to spoken theatre without the full integration of music or song, a review can include performance critique but does not constitute a specific genre of drama that combines speech and music. Thus, musicals stand out as the clear answer due to their unique combination of both elements, setting them apart from the other forms mentioned.
