Miranda Lambert is set to release her new studio album, The Weight of These Wings, on Friday (Nov. 18), but since the project is a two-disc record, fans haven't just been wondering about the meaning of the album's title; they've also been wondering about the significance of each disc's name: the Nerve (the first disc) and the Heart (the second disc). In advance of the project's release, Lambert has explained.

In two Instagram videos, Lambert shares the dictionary definitions of "nerve" and "heart," and explains why the meaning of each word connected with her.

“[Nerve] is really so much deeper than just part of your body. It’s part of your being to have nerve at all," Lambert explains. "And if you’re gonna have it, you’re gonna feel some pain from it. But you’re gonna feel some great stuff, too.”

The Weight of These Wings' first disc, the Nerve contains Lambert's first single from the project, "Vice," as well as songs such as “Highway Vagabond,” from which her 2017 tour takes its name; “We Should Be Friends,” her current single; and “Covered Wagon,” which she performed often on her 2016 summer tour.

The record's second disc, the Heart, meanwhile, features songs including “Things That Break,” “Keeper of the Flame” — from which Lambert’s summer tour took its name — and “Dear Old Sun.”

"I love that imagination is connected with heart because you would think that imagination is just your creative brain going well, but it really starts in your heart," Lambert shares ."So much of what I love as a musician, songwriter, the music that I listen to, has to do with heart."

Anticipation has been building for The Weight of These Wings, especially in light of the singer’s well-publicized divorce from Blake Shelton. The aftermath of that relationship was detailed in Shelton’s If I’m Honest, and Lambert has been clear that her album will also be … well, honest.

“Every record I’ve ever made has been a reflection of where I am right then in my life, however old I am. And I’ve never held back at all,” Lambert explains. “But this time, with what I happened to be going through in my life, being honest was never really a choice. Everybody knew anyway. So I just said, I’m gonna journal it, and — good days and bad days — use it for my art.”

Don’t expect The Weight of These Wings to be a sad breakup album, though.

“I’m never gonna have an album that’s quote-unquote a ‘heartbreak album’. Because everybody has bad moments, and then you come out of it, and you have a great moment, and then you have some somber times,” she says. “I want an emotional journey, because that’s what life is, and I want to document that.”

After releasing The Weight of These Wings on Nov. 18, Lambert will begin her 2017 Highway Vagabond Tour on Jan. 26 in Evansville, Ind.
