Guitar universal

I never thought much highly of guitar until I had one. Not only it is a difficult instrument but the most diverse too I guess. It covers a number of genres: flamenco, samba, jazz, blues, country music, rock, pop, classical. I can't recall any other instrument with such diversity. So it would not be wrong to call guitar a Universal Instrument. :) I discovered this Spanish guitar lately and developed a particular liking. In most Spanish music flat notes are used equivalent to our Raga Bhairvi. This video is particularly awesome.
