To learn Ratatat - Swisha chords, your first step should be understanding these chords - D, G, Bm, A, G, E, G, Bm, Em and Bm in sequence. I suggest starting at a calm pace of 47 BPM, and as you gain confidence, approach the song's BPM of 95. Configure the capo to your vocal range and chord preference, remembering the key of D Major.
