To learn Tengo John - Aurevoir chords, these are the chords to practise in sequence: Gm, Dm, Eb, Am, D, Eb and D. I suggest starting at a calm pace of 52 BPM, and as you gain confidence, approach the song's BPM of 105. Adjust the capo based on your vocal range and chord preference, keeping the song's key of B Major in mind.
