Taylor Swift previewed "State of Grace" from her upcoming album, Red, Monday morning on ABC's Good Morning America.

"I wrote this song about when you first fall in love with someone," 22-year-old Taylor said of the track. "It's a really big sound. To me this sounds like the feeling of falling in love in an epic way."

"State of Grace" is the fourth single from Red that Taylor has previewed on GMA, after "I Knew You Were Trouble," "Red" and "Begin Again."  "State of Grace" will be available to download Tuesday morning at 12:01 a.m.

There are 16 tracks in all on Red, ten of which Taylor wrote and six of which she co-wrote.

Red will hit stores and online outlets on October 22. Taylor will mark the release with another appearance on Good Morning America next Monday, as well as a concert performance on GMA on Tuesday.
