Composition

"Heart Shaker" is written by music production team called Galactika () and co-composed by David Amber and Sean Alexander.

Tamar Herman from ''Billboard'' described the song as a "bright pop song hatincorporates funky guitar riffs, twinkling synths, and soft harmonizing to create a vintage wintertime feel, but with an upbeat melody and impish delivery of the verses and the energetic chorus". Lyrically, the song is about a girl building up the courage to confess her love to the one who has "shaken" her heart.
