Do you mean to play chord melody arrangements? What songs? Some songs are suited to doing solo chord melody arrangements, while others are not.
[QUOTE=trungnguyen.titi94]Should i start Classical Guitar style tutorial from you now ? i think there is no way i could solo and write my music without study Classical Guitar ?

Classical will give you unparalleled insight into how music works. But if you are still in the beginner stages of technique you would do well to also work through Lisa's fingerpicking tutorials. They will give you important technique building skills to practice.

Also, it is beyond the skill set of a beginner, but if chord melody is what you are after, then jazz is an important genre to consider as well!

Best of success!
