Happiness is curating.

Pharrell Williams —the rapper, record producer, fashion designer and hat-toting singer of pop smash-hit "Happy"—is diving head first into the Paris art scene, curating an exhibition of modern art at one of the city's premier galleries.

Called "G I R L," like his most recent album, the show displays art produced by Mr. Williams's friends on the contemporary art scene, such as street artist JR and two artists known for mixing fine arts and Japanese pop culture, Takashi Murakami and a Japanese artist who goes by the name "Mr." Also in the show: Brooklyn-based painter-graphic designer KAWS, Belgian sculptor Johan Creten and French performer-sculptor Prune Nourry. The exhibition opened Tuesday and will close June 25.

Mr. Williams's latest creative exploit is a cross-pollination of his different artistic worlds. "It says 'curating by Pharrell Williams,' but it should really be 'the education of Pharrell Williams,' because I'm just learning," said the musician.

French gallerist Emmanuel Perrotin, whom Mr. Williams met in 2007, introduced him to the world of art. The idea for the "G I R L" art show came after Mr. Williams gave the album of the same title to Mr. Perrotin. Both men played with the idea of accompanying the album's launch with an art show, but the huge success of "Happy" brought the record launch ahead by two months.

Mr. Williams isn't a total novice. The musician, age 41, has already created art pieces himself and collaborated with artists on a couple of projects. His first artwork—a series of chairs with human-shape legs, made with the support of Mr. Perrotin—drew positive reviews. He then met several artists, some of whom he ended up working with on projects, as often happens with other musicians.

With Mr. Perrotin and his Galerie Perrotin team, Mr. Williams selected and commissioned art pieces around three themes, building in just 50 days a collection that spreads over two floors of an old townhouse in the chic Marais neighborhood in Paris.

First come art pieces inspired by the singer and made for the show by other artists. There's a tribute to women by a diverse array of artists with varying artistic and political views. Finally, Mr. Williams has picked works by female artists inspired by their relationship to their own bodies.

Being the subject of artworks feels "weird," said Mr. Williams. He worked on some of those pieces, including a collaboration with American artist Rob Pruitt on a couch covered with drawings related to Mr. Williams's career. The pieces of that section include a cast of the singer made of resin and covered with broken glass, by Daniel Arsham. The work required Mr. Williams to stand motionless for several hours, and breathing through a straw for a long period.

Other artworks focus on the music and videos: A painting by Japanese artist Mr. depicts Mr. Williams as a manga-style character dancing amid girls from a host of countries.

While he doesn't see himself as an activist—"I make no apology for my affinity for women"—Mr. Williams says he is a firm supporter of gender equality and doesn't hesitate to speak in favor of causes he considers worthwhile. On Twitter last week, he spoke out for the Iranian youths jailed for posting a video of themselves dancing to "Happy."
