Are you working on something that actually is a challange to you? Self composed or cover? Usually I'd say no, but I just started working on "Linus and Lucy" the Stu Hamm version. I don't tap that often/well so this is a real challange to me. I'm mainly working on one handing the bassline. I cannot get the lead to sound out at all. You must really have to pound on the string to get it to ring out, this throws off the phrasing completely. This is also hopefully going to help me seperate my way of thinking. The reason I suck at piano and drums is the extreme need to seperate your mind. Drums your feet/hands/wrists do something different from each other. Piano, left and right are working opposite each other. This being a piano piece, yikes. But the point is: I can not do this. But I'm trying. Usually I hear a bassline, learn it in a few minutes, that's it. This is hard, I can not do this. What can you not do but are trying?
