This is my comment from the sand man video– “I am so upset, i cannot do the b7 part because when i try the cords dont make sound and only the thirtd string will. I dont know if my fingers just arent long enough, if my ukeleles strings are too hard to press onto (which they are quite difficult to press on all with 1 finger) or what. I need assistance and anything would help”
Sounds like you need to adjust your form so that you have a better balance in finger strength. Check out form 3 in our lesson on proper left hand form. Should resolve this issue. Let me know how it goes 🙂
