To learn 이소라 - Tears chords, your first step should be understanding these chords - Abm, Gbm, E, A, Abm, Gbm, A, B and E in sequence. I suggest starting at a calm pace of 70 BPM, and as you gain confidence, approach the song's BPM of 140. Configure the capo to your vocal range and chord preference, remembering the key of A Major.
