The music earned the series a total of four Emmy nominations: in 2008 for the main title theme and for the song "I Ain't Got Rhythm" from the episode "Dude, We're Getting the Band Back Together", and in 2010 for the song "Come Home Perry" from the episode "Oh, There You Are, Perry" as well as one for its score. Phineas and Ferb follows structural conventions that Povenmire and Marsh developed while writing Rocko's Modern Life, whereby each episode features "a song or a musical number, plus a big action/chase scene." Both creators had musical backgrounds, as Povenmire performed rock and roll in his college years and Marsh's grandfather was the bandleader Les Brown.

Origins Early inspirations Dan Povenmire attributes the show's genesis to his childhood in Mobile, Alabama, where his mother told him to never waste a day of summer. To occupy himself, Povenmire undertook projects such as hole-digging and home movie-making. Povenmire recalled, "My mom let me drape black material all the way across one end of our living room to use as a space field. I would hang little models of
