To learn U2 - Zooropa chords, anchor your practice on these foundational sequence of chords - G#, D#, Fm, C#, D#, C# and G#. I suggest starting at a calm pace of 51 BPM, and as you gain confidence, approach the song's BPM of 103. To match your vocal range and chord inclination, adjust the capo in line with the key: G# Major.
