Beginning with the gentle whisper, 'Hey boy,' the song transitions into a hip-hop beat which integrates instrumentations of snaps accompanied with the predominant whistling melody. Stylistically, 'Whistle' has been described as a hip-hop number with a dreamy rhythm and a mature feel, integrating whistle hooks over a minimal drum 'n' bass melody. Ĭomposed in the key signature of B major, the track contains a tempo of 103 beats per minute and has a runtime of 3:31.

A Japanese version of the song was included as part of the group's first eponymous Japanese EP, which was released on August 29, 2017, by YGEX.
