Miller, a Burbank resident, has been in the performing arts since she was 15 years old.
She's been in musical theater, has danced in Las Vegas and Atlantic City and written songs for Disney shows.
"The way I write music is influenced by my performance," Miller said. "It's a conglomerate of my musical history."
But Miller never thought she'd be asked to write a song for Sesame Street, a children's television program.
Writing a children's song does have its challenges, she said.
"You have to think about the characters when you are writing," Miller said. "That's one of the challenges."
When it comes to the task of writing for children, Miller has her own solution.
"There have been times that I'm writing and I have to dance in my living room to become the characters," she said.
The song, "Another Sunny Day," is a continuation of the Sesame Street theme song, which emphasizes the fact that "even an ordinary day can be an extraordinary one," Miller said.
Miller also puts her songwriting skills to use at her church.
As the musical director of the Unity Church of Burbank, she is the lead soloist and writes the congregational music for the choir.
"She's incredibly magnetic and upbeat and she has this extraordinary capacity to find the themes in a song and she makes it appear as if it's being sung for you," said Christine Coyle, Miller's friend and a church congregant. "You are so emotionally charged after she sings, whether if it's an upbeat song or if it's an introspective, thoughtful song."
Brian Donohoe, another church congregant, said he's impressed by Miller's singing and songwriting talent.
Donohoe recalled that at a recent Sunday service, Miller wrote a song for the choir on the morning of the service.
"Each and every Sunday is an inspiration," Donohoe said. "The music is something that is totally an enlightening experience."
