In 2024, Brianna Mazzola, Nori Moore, and Wennely Quezada all individually auditioned for a place in a band on the
Netflix competition series
Building the Band. Moore performs under the name Nori Royale and was midway through a gap year at the time, while Mazzola was from
Philadelphia and Quezada is of
Dominican descent. The pair initially connected with two other contestants, Moore and Bri Gilyard, before dismissing Gilyard as they wanted to form a trio in the vein of
Destiny's Child and
TLC. The group individually rehearsed for a performance of "
Levitating" by
Dua Lipa; their performance of the song marked the first time the members met. The band took their name from a
portmanteau of 'three' and 'frequency', a reference to Mazzola's makeup incorporating an audio wave. They then performed
SZA's "
Kill Bill",
Muni Long's "
Made for Me",
Billie Eilish's "
Bad Guy", and
Brandy Norwood's "
Have You Ever?" on the programme. 3Quency reprised their "Made for Me" performance for
Netflix Summer Break, a promotional vehicle for participants of other Netflix shows broadcast seven episodes in. Long and three other bands from
Building the Band also performed. and won the show's $500,000 prize. The band announced that they had signed record deals with
Sony Music and
Columbia Records in August 2025 and released their debut single the following month. A
contemporary R&B song, "Top Down" was produced by
TBHits and was about sex. The band subsequently toured with Soulidified, another group formed on
Building the Band. In November, they released the singles "Once I Was A Good Girl" and "Clique"; the former was a song about heartbreak co-written by
Raye and
Steve Mac. They also released a take on
Donny Hathaway's "
This Christmas" around that time and their track "Telephone" in March. ==Discography==
