"Click" is a synthpop song with instrumentation from a synthesizer. It is set in common time and moves at a tempo of 135 beats per minute in the B-flat majorkey throughout the song. The introduction starts with the synthesized music accompanying ClariS' vocals, and uses a bridge to transition into the first verse, followed by the chorus. After another bridge, this pattern is repeated for the second verse and chorus featuring the same music with different lyrics. A break is used to transition into the third verse, immediately followed by a short fourth verse. The chorus is used as the outro, and an instrumental coda is used to close the song.
