A wavy line in front of a chord means to play the notes quickly in order, as opposed to simultaneously; to give a chord a harp-like effect. A rolled chord is a type of broken chord. It is a chord whose notes are played one after another beginning at the bottom. Use first and fourth fingers on all the broken fourths in the left hand and first, second, third and fourth fingers on F, F sharp, G and G sharp in the right hand.
