Let's start jamming 東京混声合唱団 - 海ゆかば chords, familiarize yourself with these chords - F, C, G, C, Am, C, E and Am in sequence. I suggest starting at a calm pace of 73 BPM, and as you gain confidence, approach the song's BPM of 146. Fine-tune the capo based on your vocal range, ensuring it complements the key of G Major.
