LARGO, Fla. — While most kids are finishing off their spring breaks, one of the people they look up to on YouTube Jack Hartmann is still hard at work preparing for an Easter “Bunny Bash” concert this weekend.

What You Need To Know

  •  Jack Hartmann calls the Bay area his home

  •  His more than 4 million YouTube subscribers and many others have watched 100s of millions of his videos

  •  Hartmann splits his days with school visits, live concerts, and recordings at his Largo studio

Here is a Day in the Life of a Rockstar to your children.

Hartmann teaches them the ABCs and other educational material at the preschool and primary level.

Usually, Hartmann begins his day with a campus visit.

Spectrum Bay News 9 caught with the viral video sensation on a visit to River Ridge High School, which is part of Pasco County Schools where several elementary-level classes attended a recent rock concert.

“So, we do that early then we come back here,” said Hartmann. “And sometimes I’ll even be writing a song in the car as I drive.”

Then it is studio time for the Jack Hartmann experience.

He’ll work with his staff recording music videos for the Jack Hartmann — Kids Music Channel on YouTube.

The studio is in Largo, but his YouTube reach is the world.

With more than 4 million subscribers and hundreds of millions of views, Hartmann is one of the biggest stars on the platform.

“We’re very educationally based,” he said. “My wife is a former kindergarten teacher, so we tried to do things that teachers really need and will help the children learn and have fun.”

He will go through several wardrobe changes in a day.

“I write all kinds of songs,” Hartmann said as he showed his different outfits. “We play dance songs. I’ve got my fancy dance jacket here. Check that out.”

In the 1980s, while moonlighting as a singer and getting his child psychology master’s degree from the University of Florida, Hartmann’s wife asked him to play songs for a younger audience.

He has been doing it ever since.

Obviously, YouTube has grown his fanbase beyond the Bay area.

During the pandemic, most assuredly Hartmann was playing in many homes as kids listened and learned.

“So, we really try to integrate learning with movement,” he said.

He is also moving hearts and lifting spirits and that’s what makes him feel good too.

“My wife always tells me, ‘Jack, go out and make them smile,’” he said. “So, if we can make them smile and have fun for that hour, it touches my heart. And then beyond that the teachers use it for learning.”
