On May 3, individual teaser photos of Nayeon, Sana, and Dahyun were uploaded, alongside the full track list for the album revealing six songs in total.

Composition

''Signal'' is an EP consisting of six songs incorporating various genres such as pop dance, hip hop, moombahton, and jazz, among others. The eponymous title track was written and produced by Park Jin-young, which featured the usage of a Roland TR-808-style kick alongside elements from hip hop and pop dance. Lyrically, it expresses a girl's frustration who keeps sending "signs and signal" to hint her feelings for a guy but is unnoticed.

The second track "Three Times A Day" is an up-tempo track that lyrically portrays the feelings and thoughts of a girl who has grown frustrated due to the indifference of her boyfriend, and sonically features moombahton and reggaetón stylings. "Only You" is a song written by former Wonder Girls member Ha:tfelt, is described as a pop song combined with hip hop. The song "Hold Me Tight" features the usage of synth music and lyrically talks about a girl's sorrow of hoping for a quick confession from her romantic interest who is oblivious to her feelings. "Eye Eye Eyes" describes the feeling of infatuation, and was written by Jihyo and Chaeyoung while featuring an overall upbeat sound which was contrasted by a jazz break in the middle of the track. The album's closing track, "Someone Like Me" is described as a soft pop song featuring the usage of an electric guitar and is said to be a continuation of the song "One In A Million" from the group's previous release, '' Twicecoaster: Lane 1''.

Promotion

JYP Entertainment denied the report about the group's plan to promote the EP for only two weeks due to their Japanese debut in June. Twice's leader Jihyo, who took a break from activities due to a knee injury, re-joined the group for promotions.

On May 3, 4 and 9, Twice recorded an episode of ''Weekly Idol'', ''Knowing Bros'' and ''Top 3 Chef King'', respectively. Twice held a media event at Blue Square Samsung Card Hall in Hannam-dong, Seoul before the release of the EP. The group also had a comeback showcase with fans two hours after the release, where they performed "Signal" and other songs from their previous albums like "Like Ooh-Ahh", " Cheer Up" and more. It was broadcast live via Naver V Live.

The group promoted their album in several South Korean music programs, starting with their appearance on ''M Countdown'' on May 18.
