Let's start jamming 張敬軒 - 斷點 chords, practice the chord sequence Gm, Eb, F, Bb, F, Gm, Bb and F. I suggest starting at a calm pace of 50 BPM, and as you gain confidence, approach the song's BPM of 100. Considering the song's key of Bb Major, position your capo to suit your vocal and chord preferences.
