"Heartbeat" is a song recorded by American singer and songwriter Carrie Underwood from her fifth studio album, Storyteller.

Musically, "Heartbeat" is a country pop and a R&B song with lyrics that relate to the feeling of intimacy experienced by being alone with one's lover.

"Heartbeat" is a country pop[1][2] and R&B[3] song written by Carrie Underwood, Ashley Gorley, and Zach Crowell.

[5][6] Country singer Sam Hunt, who is a frequent collaborator of Crowell's, sings backing vocals on the track, leading some publications to label the song a duet.

[1][6] Described as "the most real love song" Underwood has recorded, the lyrics of "Heartbeat" relate to the feeling of intimacy experienced by being alone with one's lover.

[3][5][6] Critics noted a thematic similarity to then-recent single "Smoke Break" in that the song encourages finding time in a busy life for a private moment of bliss.

Will Hodge of Rolling Stone opined that, "Underwood is known for creatively blending intimate lyrics with bombastic choruses and the power-ballad boom of "Heartbeat" is no exception.

Her molasses-smooth vocal delivery sets the mood, leaving the listener feeling as if they're eavesdropping on someone else's date night."

He concluded his review by saying, "Carrie Underwood tackles the subject matter in "Heartbeat" with much delicacy and sentimentalism.

"[9] Country Weekly awarded the song a B+ and commented, "Carrie interprets the message with real conviction and a passion that hits the right emotional notes without going overboard.

The video shows Underwood in a sparkly gold flowing dress, walking barefoot through a lush forest, humming the melody of the song.
