Keyboards: Keyboards are used to play the melodic lines and harmonies of the song. The main melody of the chorus, "Hey, I just met you, and this is crazy, but here's my number, so call me, maybe," is played on a synthesizer with a bright and catchy tone.
Drums: The drum set provides a steady rhythm and groove to the song. The drums play a simple but effective pattern that includes hi-hats, snare, kick drum, and toms.
Bass guitar: The bass guitar plays a supportive role, providing a low end foundation for the other instruments. It follows the chord changes and adds a sense of warmth and depth to the song.
Synthesizer: In addition to the keyboards, a synthesizer is used to create additional electronic sounds and effects. For example, the synthesizer is used to create the shimmering background pad during the chorus and the synth bass that accents certain sections of the song.
