Listen to a simple recording (anything but Lady of Spain)

Foolstroupe gives excelent advice:

You should hear the:
Caaa, Cunk, Cunk,
Caaa, Cunk, Cunk,
Gaaa, Gunk, Gunk
Gaaa, Gunk, Gunk
Faaa, Funk, Funk
Faaa, Funk, Funk
Caaa, Cunk, Cunk Cunk

Clean and clear in the 3/4 time of the rhythem. Fingers are usually fully released until you develop a style for a particular piece. Folk most anything folk....the are arranged in an easy convenient pattern for progressions.

Sincerely,
Gargoyle
