Yeh.. I never know if I am training myself correctly.. am I holding the pick properly? am I hit the strings correctly? have I got into a bad habit that I am not aware of that is stunting my speed? I play and play and play but I am sort of locked into around the 150bpm mark and cannot go any faster.. The exercises themselves are helpful but there are all these little basic questions not answered. If I am holding the pick incorrectly that could be the problem.. I have watched a lot of YouTube and other tutorials on alternate picking and they seem to hold the pick between thumb and index finger but on an angle. Each instructor uses a slightly different angle of attack. Also, when I do alternate picking, the depth/height of where my plectrum is between string strikes raises slightly, as if I am going to move over the string before striking another string.. but I do this even on the same string.. should the height of the pick stay the same and more of a shredding/rhythm playing style be used?
