Yummy

The harmony in 'Yummy' is deliberately static: a single four-chord loop in D minor anchors the entire production, consistent with the loop-based construction that defines late-2010s and early-2020s trap-R&B. No modulations, no secondary dominants, no chromaticism. The interest is entirely timbral — the interplay between Bieber's rap-inflected pre-chorus delivery and the falsetto he reaches for in the bridge — which means a guitarist or pianist can reproduce the harmonic skeleton with one afternoon of practice.

Bieber first surfaced the title on October 27, 2019, hand-writing 'Yummy' on paper for an Instagram post, then teased the genre label 'R&BIEBER' the following day. The song was built in sessions with Kid Culture, Poo Bear (Jason Boyd), Sasha Sirota, and Ashley Boyd ahead of the album cycle that would become Changes.

Released January 3, 2020 as the lead single from Changes, 'Yummy' ended a nearly four-year silence from Bieber as a solo artist. Built on pop-trap beats, a crisp bass line, and plinking keyboards, the track is an unambiguous ode to newlywed life with Hailey Bieber. It debuted at number two in the United States and reached number one in New Zealand.
