This dance isn't only about romantic relationships, however. In Three Is a Party - which features three linked figures and a fourth, disconnected one - he explores the intellectual connection between people, perhaps friendship.
Although the connected figures have an intensity to their connection, it's the fourth figure who is more at peace with themselves because they are free of the pressures that come with social interaction.
Says Pieroth: "These figures are struggling. They have company but they also have the disadvantage of the struggle [that comes with it]. I can relate to that a lot. Even with social life, sometimes you want to be part of it but ... there's so much energy flowing and you have to process all that.
"Sometimes you want to take a break ... and not do anything social."
One of Pieroth's most striking works is also the starkest.Temptation, which features a shapely, mostly naked female figure with thorns coming out of her breasts, is erotic but not sexy.
"It speaks to temptation in general, because if you touch the breast you might get hurt.
"Temptation's a tricky thing," he says. "The apple that she's reaching for with her tongue, that is the apple from the Bible but it's also Apple the company. This stands for a society of consumption. We're always tempted by consumption. We're always eager to get the new thing, the more expensive thing, but none of it is real."
Another one of his works is Lost in a Good Space, featuring two dark figures having an emotional tug-of-war against a vibrant background.
"I used all these colours and strokes to give it a floating energy. The energy is in the background," he says.
"You can see that they are really trying to get away from each other, but they can't. It's not a good connection that they have and they both know it and it's hard to get away from each other.
"But they shouldn't be afraid of disconnecting because this surrounding they're in is pretty nice. It's colourful, it's vibrant. Sometimes people are scared of letting go. Everybody's too scared of being alone. But there is a beautiful world out there, so just let go."
Relationships - be they romantic or otherwise - are often the best muse in art and the many forms it takes.
"In general my work is about how people interact and connect; how they link up. How they need each other. Nobody wants to be solitary. But then all kinds of connections and relationships are tricky as well.
"It's not that easy so we find [ourselves in] very toxic relationships. There's an interdependency that's not good for you. Both people know it but they can't let go ... Everywhere I look I see that. We can be the most loving people on earth but also do the most fucked-up shit to each other."
Pieroth is part of a group exhibition, 'Open Studio', at Johannesburg's August House, opening on March 26.
