Right now I am playing simple chords, "G" for example. I use my ring finger on the 3rd fret. When I go to change to "simple c", I lft my ring finger and place my index finger on the first fret. In that time when I am lifting my ring finger to the time I am placing my index finger, the neck pulls away due to the presure my right arm has on the body of the guitar and nothing holding the neck.
