Returning from lesson n.7 which included the execution of some left hand alone parts, we complete exercises for left hand with other four variations ( the n .5-6-7-8) . Variation No.5 introduces chorus . This song part must be repeated once. Beats that have to be repeated are framed by two vertical slashes with two points (left and right). A double slash with both left-facing points must be repeated since the beginning once, then move to the next beats. Listen to the song seeing the score will clarify your ideas.
Regarding times the advice is always what I said in lecture No.5, musical figures of the pattern are repeated constantly from beat to beat, for each variation . If you got here reading, there should be no problems.
