To jam and learn the simple chords for The One - 잘있나요 chords, practice playing B, F#, A#, D#m, C#, F#, B, F#, A#m, D#m, G#, C# and F# in sequence. I suggest starting at a calm pace of 69 BPM, and as you gain confidence, approach the song's BPM of 138. To match your vocal range and chord inclination, adjust the capo in line with the key: E Major.
