To learn Marshmello - Vibr8 chords, focus on the sequence of these chords: F, Am, Dm, F, Am, G, Dm and Am. I suggest starting at a calm pace of 57 BPM, and as you gain confidence, approach the song's BPM of 115. Adjust the capo based on your vocal range and chord preference, keeping the song's key of F Major in mind.
