Let's start jamming Billfold - (feat. Seeon Under18) Sama chords, familiarize yourself with these chords - G, Bb, D, A, D, G, F and D in sequence. A good strategy is to initiate at 75 BPM and then accelerate to the track's regular speed of 150 BPM. To match your vocal range and chord inclination, adjust the capo in line with the key: D Minor.
