To learn Spitz - Gunjyo chords, these are the chords to practise in sequence: G, D, G, A, D, Bm, A, D, G and Bm. A strategic approach would be to train at 75 BPM initially, and then accelerate to the song's tempo of 150. Given the song's key of D Major, adjust the capo to align with your vocal range and chord preference.
