To learn Filter - Gerbil chords, your first step should be understanding these chords - Bm, Bb, G, D, C, B, Bb, B and G in sequence. I suggest starting at a calm pace of 82 BPM, and as you gain confidence, approach the song's BPM of 164. Fine-tune the capo based on your vocal range, ensuring it complements the key of G Minor.
