To start learning Radau - (Bonus Track) Rittersong chords, build your understanding on these basic chords - Em, D, Em, G, D, E and G in sequence. I suggest starting at a calm pace of 52 BPM, and as you gain confidence, approach the song's BPM of 104. To match your vocal range and chord inclination, adjust the capo in line with the key: D Major.
