To jam and learn Vso - Bn chords, your primary focus should be mastering these chords sequence: Ab, Fm, Cm, Gm, Ab, Cm and Ab. I suggest starting at a calm pace of 56 BPM, and as you gain confidence, approach the song's BPM of 113. Fine-tune the capo based on your vocal range, ensuring it complements the key of Bb Major.
