To learn Marie Laforêt - Je Vois chords, your first step should be understanding these chords - Dm, G, C, G, C, F, Dm and C in sequence. I suggest starting at a calm pace of 58 BPM, and as you gain confidence, approach the song's BPM of 118. Configure the capo to your vocal range and chord preference, remembering the key of C Major.
