To start learning Keenv - Toi Et Moi chords, build your understanding on these basic chords - F, C, F, Bb, C, F, Dm and Bb in sequence. I suggest starting at a calm pace of 45 BPM, and as you gain confidence, approach the song's BPM of 90. Configure the capo to your vocal range and chord preference, remembering the key of Bb Major.
