To learn Giorgos Zambetas, Stelios Zafeiriou - Siko Horepse Sirtaki chords, these are the chords to practise in sequence: Bb, F, C, F and Bb. I suggest starting at a calm pace of 45 BPM, and as you gain confidence, approach the song's BPM of 91. Adjust the capo based on your vocal range and chord preference, keeping the song's key of F Minor in mind.
