Tonight's the night (Thursday, December 5th)! Carrie Underwood plays her dream role of Maria von Trapp in the live television broadcast of The Sound of Music. Carrie has been learning the lines, the music and even a few dance steps for the three-hour show, which airs on NBC beginning at 8 p.m. ET.

Before you tune in, however, Carrie wants to make one thing perfectly clear -- this is NOT an adaptation of the movie version of the beloved classic. 

The Sound of Music Live! soundtrack is currently in stores.

The DVD will be released on December 17th.

Carrie was featured on NBC's Today show this morning.
