To learn Darso - Rumasa chords, your practice should emphasize these chord progressions: Abm, Dbm, Eb, E, Abm, Eb, Abm, Dbm and E. I suggest starting at a calm pace of 80 BPM, and as you gain confidence, approach the song's BPM of 160. Fine-tune the capo based on your vocal range, ensuring it complements the key of Eb Major.
