To learn The Sidh - The Silk Road chords, your practice should emphasize these chord progressions: C, Cm, G, Ab, Bb, Ab, Ab, F and Cm. I suggest starting at a calm pace of 65 BPM, and as you gain confidence, approach the song's BPM of 130. For a balanced pitch, adjust the capo with respect to your voice and the song's key: Bb Major.
