A band spokeswoman told news outlets the band was notified at the last minute that Beyonce would perform to the pre-recorded music. The band played their instruments live.
All inaugural music is pre-recorded in case weather conditions or other circumstances could interrupt the programme.
A representative for Beyonce did not immediately respond to requests for comment. Kelly Clarkson's representative said she sang live to perform My Country, 'Tis of Thee.
The use of a recording is typical in big events.
