To learn Slowdive - Sing chords, your practice should emphasize these chord progressions: D, Am, G, F, G, F, E, D, Am, B, C, G, C, Bm and G. A strategic approach would be to train at 69 BPM initially, and then accelerate to the song's tempo of 139. Configure the capo to your vocal range and chord preference, remembering the key of G# Major.
