Before opening the show off-Broadway, Duncan Sheik had composed an arrangement of song demos for the original concept of Spring Awakening. Back then the musical's plot adhered more closely to the original play's plot. Steven Sater and Duncan Sheik had originally intended for Melchior actually to rape Wendla at the end of "I Believe," but decided to change that plot because he wanted the scene to be more loving between the two characters. In workshops, "I Believe" ended with Wendla's scream while being raped. "All That's Known" replaced a song titled "All Numb". Both songs had the same theme, but because the directors had to reduce time for the show, "All Numb" was cut and replaced with "All That's Known". A song called "A Comet on Its Way" was replaced by "The Bitch of Living". Although both songs followed the same basic theme, Sheik thought that "The Bitch of Living", being more upbeat, fit the show better. "Those You've Known" replaced a song called "The Clouds Will Drift Away", which was cut because Sheik wanted the song between the three main characters to stay close to the "All That's Known" theme. "Mama Who Bore Me (Reprise)" was originally intended to be performed after "Touch Me". Another song, entitled "Great Sex" (which was intended to be performed after "Mama Who Bore Me (Reprise)"), was also cut from the show because the directors thought the song pointed out the theme of the show too specifically. It was intended to be performed during Hanschen's masturbation scene, but the song was removed and the scene moved into the middle of "My Junk". Also, in an early workshop version of the show, the song "The Dark I Know Well" was intended to be sung by Thea for currently unknown reasons. It was then changed to be a duet between Martha and Ilse. Finally, songs such as "Touch Me" and "The Mirror-Blue Night" each had a reprise, and "Mama Who Bore Me" had a second reprise. Even "There Once Was a Pirate", which was cut, also had a reprise that was sung by the girls other than Wendla.
