PBS character Xavier Riddle celebrates legendary dancer Alvin Ailey at the Whitney

Sunday will be Funday at the Whitney Museum of American Art, with a real-life version of a popular PBS Kids character joining a celebration of the late legendary dancer and choreographer Alvin Ailey.

Xavier Riddle, the main character from “Xavier Riddle and the Secret Museum,” will be part of a day of Ailey-inspired activities to drum up excitement for the Whitney’s “Edges of Ailey” show, which the museum calls “the first large-scale museum exhibition to celebrate” the famed choreographer.

The exhibit is part visual art, part live performance and part archival materials.

Activities on Sunday, which are free through the museum’s “Free Second Sundays” initiative, will include West African dance classes, live music by Jazz at Lincoln Center and a chance to snap pics with Xavier Riddle.

“Xavier Riddle and the Secret Museum” is based on a popular book, in which the title character and his friends learn about historical figures, including Ailey.

The Whitney will screen the Xavier Riddle Ailey episode and have the artist on site to teach kids and adults how to draw Ailey or any person they care about.

“Edges of Ailey” opened on Sept. 25 and consists of an 18,000-square-foot immersive exhibition with more than 80 artists on the fifth floor, and performances in the third-floor theater. It runs through Feb. 9.

Though free this Sunday, tickets are required. They can be reserved in advance at whitney.org/admission.
