Place the heel of your right hand on the bridge of the guitar. Your fingers should extend almost to the soundhole (if you have an acoustic guitar). Your hand should be in a very relaxed position, with your fingers softly touching the strings. Your hand should not feel uncomfortable. Form a normal C chord with your left hand. Place your fingers on the appropriate strings as follows: Thumb on the 5th string Index finger on the 4th string Middle finger on the 3rd string Ring finger on the 2nd string Now, practice picking with each finger. For the thumb, pick downwards using the inside edge of your thumb. For all other fingers, pick upwards using the fingertip. You can use the flesh of your fingertip or your fingernail; whichever you prefer. Practice each finger for a minute or two, never allowing the finger to leave its associated string mentioned above. Keep your hand planted on the bridge throughout this exercise. It should not be uncomfortable while picking. Eventually you will want to change your hand position so you are not muffling the bridge. By resting your hand on the bridge it deadens the sound, so you will want to move your hand off of the guitar top. To do this simply keep your pinkie sitting on the guitar top below the strings and pick like you normally do. Your pinkie will brace your hand to allow you to pick. This may be uncomfortable at first, but you will get used to it. If you find it difficult, you can always continue using the first method. You don't need to change your hand position immediately; just change it when you feel comfortable changing it.
