Question:

"Dannychoo asks, "i had asked this question on the message forum and got a response, but kinda difficult to visualize it so i thought i'd ask here again. my problem is that i have a difficult time keeping my fingers square to the fret. i've seen videos of people playing scales and their fingers are very square to the fret. mine are always kinda leaning towards one side. i'm also having problems with fingers "flailing" around... as in when my pinky is down my index finger would be like 2 inches off the fret. help please! thanks.""
