Let's start jamming 關正傑 - 惜別歌 chords, familiarize yourself with these chords - Bb, Cm, Bb, Eb, Cm, Eb, Ab, Eb, Cm and Eb in sequence. I suggest starting at a calm pace of 49 BPM, and as you gain confidence, approach the song's BPM of 99. Fine-tune the capo based on your vocal range, ensuring it complements the key of Eb Major.
