Let's start jamming 이준형 - 이글루 chords, practice the chord sequence D, G, Bm, Am, C, G, C, Bm and C. I suggest starting at a calm pace of 36 BPM, and as you gain confidence, approach the song's BPM of 74. Considering your vocal pitch and chord choices, adjust the capo in accordance with the key: G Major.
