To start learning Cmx - Kain chords, build your understanding on these basic chords - Bm, G, Bm, F#m, A, G, Em, C, G, Am and F in sequence. A strategic approach would be to train at 50 BPM initially, and then accelerate to the song's tempo of 100. Given the song's key of D Major, adjust the capo to align with your vocal range and chord preference.
