The Dadd9 chord is difficult and will give your hand a good stretch. We start by placing our index finger across the entire second fret, leaving a little of the top to hang over. When you press your finger down all strings should play clearly, if not make small adjustments in where the index is placed. Next the ring finger is stretched to the fourth fret of the C string and the pinky to fifth fret of the A string. Keep those last two fingertips straight up so they do not dampen the strings next to them. The grip may feel a little uncomfortable when you first play this chord.
