To start learning Nirvana - (1992/Live at Reading) D-7 chords, build your understanding on these basic chords - G, E, F, Dm, C, E, F and C in sequence. I suggest starting at a calm pace of 61 BPM, and as you gain confidence, approach the song's BPM of 122. Considering the song's key of A Minor, position your capo to suit your vocal and chord preferences.
