Let's start jamming Ricardo Arjona - Mi Pais chords, familiarize yourself with these chords - Em, F, G, F, G, Am, F, Am, G, C, Am and Em in sequence. A strategic approach would be to train at 67 BPM initially, and then accelerate to the song's tempo of 135. With the song's key of C Major, set your capo to fit your vocal range and chord choice.
