Hi Surenperera!
Nice tip. I learnd this after playing about two weeks, and its not advanced. I think It's like american CT says about tha language. Sure I can make myself understod in english (in spite of being swedish...) but if I get the chance to evolve with a fairly small effort I of course go for it.
In sweden the school teaches basic music so the chord progression I already knew (But I still don't think the alphabet from A to G with a few flats and sharps in between can be classified as advanced). When I started playing the guitar 6 month ago I thought it to be fairly illogical untill my friend told me to just learn the strings tuning. Start with an open string and follow the chord progression up the frets.
Then I bought an easy book called "basic music theory for guitar". It explains your tip and how to build chords out of single notes, basic scales and som other goodies. You read it throug in half an hour and suddenly the guitar is logical...
Keep learning theory, it drasticaly evolves your music language...
