What was the impact of depicting slaves as being happy and good singers?

Different genres, like movies and novels, depicted —and some continue to do so even to this day— slaves through stereotypical figures that created a sense of relief and false or complacent consciousness for those who were the dominant groups in society —white, privileged men. Through these depictions, the resistance, the struggles, the pain and suffering, and the injustices —even death itself— that slaves had to endure were sadistically undermined for the favor and comfort of those in power.
