Let's start jamming Mastodon - Oblivion chords, familiarize yourself with these chords - Eb, Gm, G, Cm, Eb, F and Eb in sequence. A strategic approach would be to train at 68 BPM initially, and then accelerate to the song's tempo of 137. For a balanced pitch, adjust the capo with respect to your voice and the song's key: C Minor.
