Let's start jamming L. Martin - 4Am chords, practice the chord sequence Gm, Fm, Bb, Eb, Fm, Eb, Bb, Fm and Gm. I suggest starting at a calm pace of 52 BPM, and as you gain confidence, approach the song's BPM of 105. Tune your capo to accommodate your vocal range, referencing the song's key: Eb Major.
