Hora Martisorului is one of the most famous Romanian dance compositions for violin composed by Grigoras Dinicu. The great Stephane Grappeli was huge admirer of Dinicu's work.
This version is adjusted for acoustic guitar in gypsy jazz style. The harmony is in that gypsy jazz style while the technique is a combination of alternate and sweep picking. I have tabbed the fingering of the left and the right hand note by note so you will be able to see the exact way of playing.
