I am on lesson one (Slurs) and notice that i have to strike the string very hard (strumming hand) in order to get the "echo" when doing the 6-8, example 1 (pg. 8-9). I do not strum HARD when I play. Will I have to learn to strum HARD like that when I play all the time. It seems like a lot of force to me which feels unnatural. Thanks.
