The acoustic outro of “My Name is Jonas” features a simple and catchy five-chord progression which follows a predominantly major tonality with a touch of minor tonality. The loop creates a memorable and recognizable melody that is widely associated with Weezer’s popularity in the alternative rock scene during the ’90s.
The chord progression in the outro of Weezer’s “Undone – The Sweater Song” follows a repeating pattern with a combination of major and power chords. The overall key of the progression is G major, and the chords follow a predictable pattern that is rooted in rock and alternative music styles. The chord progression uses borrowed chords from the parallel key of G minor, specifically the B♭ major chord.
