To learn El Tri - Pamela chords, your first step should be understanding these chords - G#m, C#m, A, B, C#m, A, B and E in sequence. I suggest starting at a calm pace of 76 BPM, and as you gain confidence, approach the song's BPM of 153. Configure the capo to your vocal range and chord preference, remembering the key of C# Minor.
