To start learning ฌา-มา - ถาม chords, centre your learning around these elemetal chords sequence: Em, G, Am, D, Em, C, D, G, Em and Am. I suggest starting at a calm pace of 43 BPM, and as you gain confidence, approach the song's BPM of 87. Align the capo with your vocal depth and chord choice, bearing in mind the song's original key: G Major.
