Final answer:
The term that describes sound which contrasts with the image is 'counterpoint,' and it is used to create a juxtaposition in a scene. 'Discordant' refers to clashing sounds but does not specifically address the contrast between the sound and the visuals.
Step-by-step explanation:
The effect being described in the question is known as counterpoint, where the sound that is heard contrasts or goes against what is being seen, creating a disconnect or juxtaposition in the medium. Examples such as a merry tune over a funeral procession highlight this by delivering a sonic experience that is incongruous with the visual cues presented. Therefore, the correct answer to the question would be 'c) Counterpoint.' While 'b) Discordant' also describes a musical mismatch, it refers more to a combination of sounds that clash due to their frequencies, like the warbling sound produced by two similar but not identical piano notes being played together. This sonic warbling is an example of beats, resulting from constructive and destructive interference of the sound waves.
