Contrast : Opposition or juxtaposition of different forms, lines, or colors in a work of art to intensify each element’s properties and produce a more dynamic expressiveness.
We can definitely talk about contrast when hearing name of song. The alternation between agressive and relaxing parts, the use of natural and synthetics sounds, it’s all part of the “contrast making” process.
So what’s the use of putting contrast?
To enhance the impact of one effect.
It’s a common beginner mistake to think that if you want to add punchiness to your song, you should pile up loud and agressive parts. But if everything is loud, how are you gonna feel the punch? Your ear is gonna get used to this loudness and perceive everything as the normal intensity. Most people will just turn down the volume. Contrast should be used to achieve the effect. In name of song, the powerful intro makes the first verse even more relaxing, and vice-versa.
Contrast is not a magical solution though. The risk is to combine sounds that don’t compliment each other, like drinking a nice red wine after brushing your teeth with your super mint toothpaste. There would be a high contrast between the two, but the result is desastrous, believe me…
Experiment is the key, listen to what you’ve found, does it correspond to your intent? Is name of song a punchy or a relaxing tune?
