Jason Mraz · from We Sing. We Dance. We Steal Things., 2008
The sunny, reggae-tinged singalong in the key of G — the whole song rides the I–V–vi–IV loop of G, D, Em and C, all easy open shapes. Played with no capo, so guitar, piano and bass all use the exact same chords. Every diagram below is sourced live from the chord library.
Open I'm Yours on the interactive piano, hear every chord, and loop the progression.
Play I'm Yours in the Studio →G major. The whole song loops the classic I–V–vi–IV — G (I), D (V), Em (vi) and C (IV). There is no capo, so guitar, piano and bass all play these same chords at the same pitch.
Yes. I'm Yours is played with no capo in the key of G, so there's no transposition — the piano plays the same G, D, Em and C the guitar does, looping through the same I–V–vi–IV all song long.
