[[File:Fred Rogers and Daniel Tiger.jpg|thumb|left|The character Daniel Tiger is based on Fred Rogers, and elements of his home are based on the set of ''[[Mister Rogers' Neighborhood]]''.]]
The series centers around Daniel Tiger (son of Mom Tiger and Dad Tiger). It also features other children of the characters from the [[Neighborhood of Make-Believe]], such as Katerina Kittycat (daughter of Henrietta Pussycat), Miss Elaina (daughter of Lady Elaine Fairchilde and Music Man Stan), O the Owl (nephew of X the Owl) and Prince Wednesday (King Friday and Queen Sara Saturday's youngest son and Prince Tuesday's little brother). Two 11-minute segments are linked by a common socio-emotional theme, such as disappointment and sadness or anger and thankfulness. The theme also uses a musical motif phrase, which the show calls "strategy songs,", to reinforce the theme and help children remember the life lessons. Many of the "strategy songs" are available in albums or as singles under the artist name "Daniel Tiger's Neighborhood.".<ref>The first two albums are ''Big Feelings'' and ''Life's Little Lessons.''{{Cite web|url=https://www.amazon.com/s?k=Daniel+Tiger%27s+Neighborhood&i=digital-music|website=www.amazon.com|access-date=2019-07-26|title=Amazon.com: Daniel Tiger's Neighborhood: Digital Music|archive-date=2023-07-22|archive-url=https://web.archive.org/web/20230722024147/https://www.amazon.com/s?k=Daniel+Tiger%27s+Neighborhood&i=digital-music|url-status=live}}</ref> The program is targeted at preschool-aged children; it teaches emotional intelligence, kindness, and human respect.
