Final answer:
The soundtrack of a film comprises all the audio elements including dialogue, sound effects, and music, while the score refers specifically to the background music composed for the film. The correct answer is a) Soundtrack, score.
Step-by-step explanation:
In the context of early sound films, the soundtrack includes all of the dialogue, sound effects, and music of a film, whereas the score refers to the music only. Therefore, the correct answer is a) Soundtrack, score.
The term soundtrack encompasses the complete audio component of a film. It is an integral part of the movie-going experience, as it not only includes the actors' voices but also the sound effects created by Foley artists, and the overarching musical themes composed specifically for the film, which are instrumental in setting the tone and enhancing the audience's emotional engagement with the narrative.
The score, on the other hand, signifies the music composed for a film, which seamlessly underscores the scenes and provides atmosphere. This musical element is carefully selected or composed by the Sound Designer to align with the film's style and era, significantly contributing to the film's emotional and narrative depth.
