Let's start jamming Só Pra Contrariar - Domingo chords, practice the chord sequence Am, Cm, F, Bb, Bbm, Am, G, Bb, Am and D. A strategic approach would be to train at 42 BPM initially, and then accelerate to the song's tempo of 86. Tune your capo to accommodate your vocal range, referencing the song's key: F Major.
