To start learning Au5 - Lush chords, centre your learning around these elemetal chords sequence: C#, F#, A#m, C#, G# and A#m. I suggest starting at a calm pace of 70 BPM, and as you gain confidence, approach the song's BPM of 140. For a balanced pitch, adjust the capo with respect to your voice and the song's key: A# Minor.
