Let's start jamming Os Tubarões - Tunuca chords, familiarize yourself with these chords - C, Bb, Am, A, Bb, A, Am and Bb in sequence. A strategic approach would be to train at 72 BPM initially, and then accelerate to the song's tempo of 145. Adjust the capo based on your vocal range and chord preference, keeping the song's key of F Major in mind.
