Let's start jamming Grupo Firme - Deja chords, familiarize yourself with these chords - Eb, Ab, F, Eb, Gm, Ab, F, Bb, Eb, Ab and Bb in sequence. A good strategy is to initiate at 68 BPM and then accelerate to the track's regular speed of 136 BPM. Align the capo with your vocal depth and chord choice, bearing in mind the song's original key: A Major.
