I have a few problems. I cant seem to stretch my fingers far enough to get to the right frets in the right time. Like for instance. On somke on the water, I hold down the third fret of E with my first finger, but then I need to get to the sixth fret with my third finger...but it doesn't reach. Also, when I swith frets, the note dies or vibrates or squeaks when my finger hits it. Why is this? I have only been at this for a short time...help...please...
