Cool

"Cool" relies on a simple diatonic major-key loop — the harmonic content is never the focal point. What separates it from a generic pop exercise is Tedder and Skelton's production: a funk-inflected rhythm section, syncopated guitar figures, and stacked backing vocals (all six writers contributed) shift the feel from straightforward chord-strumming into something with physical groove. The harmony exists to stay out of the way and let the sonic texture do the work.

"Cool" was written by all three Jonas brothers — Nick, Joe, and Kevin — alongside Ryan Tedder, Zach Skelton, and Casey Smith. Tedder, the OneRepublic frontman with production credits spanning Adele's "Rumour Has It" to Beyoncé's "Halo," brought a melodic economy to the session that kept the song focused and radio-ready. The lyrical premise — a narrator cataloguing why life feels effortlessly good — mirrored the brothers' own headspace returning to music after a six-year hiatus.

Released in April 2019 ahead of Happiness Begins, "Cool" finds the Jonas Brothers in full pop form — confident, upbeat, and unashamedly catchy. Produced by Ryan Tedder and Zach Skelton, the track layers a vintage funk-inflected groove under polished modern pop sheen. It announced that the brothers' reunion was a genuine creative fresh start, not a nostalgia exercise.
