Let's start jamming やなわらばー - 花 chords, familiarize yourself with these chords - Am, Dm, Bb, C, F, Dm and C in sequence. I suggest starting at a calm pace of 82 BPM, and as you gain confidence, approach the song's BPM of 164. Set the capo considering your vocal range and favored chords, aligned with the key: F Major.
