Even though it is title as an opera, "The Devils of Loudun's" dramatic style is influenced by other genres. While the use of chorus, soloist, and orchestral fragments all adhere to the operatic tradition, the influence of theatrical genres is evident on the operas' extensive use of speech. To this effect, the libretto, divided into 32 scenes, may also be regarded as a byproduct of a theatrical influence. In addition, it is possible to perceive some elements of comic opera in the male-voice quartet at the end of the second act; while the reference to the Passion play is obvious on the martyrdom figure of Grandier.
