To start learning Chaos Z - Gewalt chords, build your understanding on these basic chords - C#, A#m, C#, F#, A#, F and C# in sequence. I suggest starting at a calm pace of 45 BPM, and as you gain confidence, approach the song's BPM of 90. Adjust the capo based on your vocal range and chord preference, keeping the song's key of C# Major in mind.
