To learn Range - Relax chords, your practice should emphasize these chord progressions: Bb, Eb, Bb, C, Gm, Bb, Eb and F. I suggest starting at a calm pace of 80 BPM, and as you gain confidence, approach the song's BPM of 160. With Eb Major as the song's key, tweak the capo to cater to your vocal pitch and chord likes.
