orchestral authenticity. Goldsmith's long-time assistant Neal Acree started composing additional music for Stargate SG-1 in Season 8. The amount of composed music varied between 12 and 33 minutes out of a 44-minute episode, with an average of around 22 to 26 minutes, making the full symphonic score of SG-1 more time-consuming to create than for general TV shows. Since Goldsmith lived a thousand miles away from Vancouver, he and the producers discussed ideas over the phone and exchanged tapes via Federal Express for several years until the show switched to Internet file transfers. Goldsmith's reliance on Arnold's score decreased over the seasons when Stargate SG-1 departed from the Goa'uld theme and introduced new characters and races. Goldsmith had a thematic approach to races and spaceships. For example, he wanted a mechanical, repetitive musical motif for the Replicators; Gothic, Gregorian and Christian themes were the inspiration for the Ori motif. The Ancient theme was deliberately carried over to Stargate Atlantis. The end of "Lost City" has a basic melody that would become part of the main title of Atlantis per a suggestion by Goldsmith's assistant. Non-original music was rarely used on SG-1, although Goldsmith chose the aria "Vesti la giubba" from Leoncavallo's Pagliacci for season 3's "Shades of Grey". Additionally, Lily Frost's song "Who am I" played in Season 7's "Fragile Balance" and CCR's song "Have You Ever Seen the Rain?" played in the series finale "Unending". A television soundtrack with Goldsmith's adapted score was released in 1997, followed by a best-of release in 2001. In Season 1 Episode 7, "The Nox", the music that played when The Nox appeared was Spinning The Silk from the album Chrysalis by 2002. Opening title sequence Stargate SG-1 has had several opening title sequences, which are generally preceded by a teaser act. The credits are normally sixty seconds long. Richard Dean Anderson was the only SG-1 actor whose name appeared before the show's title. Michael Shanks' name was moved near the end of the opening credits with the appendage "as Daniel Jackson" after his return to the show in Season 7. Some DVD versions of early SG-1 seasons have different opening credits from the television versions, as do the direct-to-DVD films. Composer Joel Goldsmith adapted David Arnold's Stargate feature film score for SG-1s opening title theme, which remained the same during the run of Stargate SG-1 and its direct-to-DVD films.
