To start learning Hashim - Al-Naafyish chords, build your understanding on these basic chords - Bb, G, Eb, G, Cm, G, F and G in sequence. A strategic approach would be to train at 62 BPM initially, and then accelerate to the song's tempo of 126. Fine-tune the capo based on your vocal range, ensuring it complements the key of G Minor.
