This song is probably one of the most beautiful pieces ever written for classical guitar. It has some difficult parts with Barre chords but definitely worth it to learn this piece. This song is alos commonly called Spanish Romance.
I chose to not record my tutorial cause this tutoral is pretty spot on!
