We have to learn the position of the note on the guitar. After that if we already do that well we just need to learn about the technique that we should use. I will use La Cumparsita for song because it has so many technique that we can use to play the song like apoyando, tremolo, arpeggio, and tone color/tone quality picking skills, harmonic skills, slur, sincronize skills between left hand and right hand.
