Transitioning Between Chords
Note that many of the popular basic chords involve fretting a string with the same finger at the same fret. When transitioning between two of these chords, it is helpful to keep that finger fretted and to use it as an anchor for your hand while the other fingers move to the new positions. For example, the chords A minor and C both involve using the index finger to fret the B string’s first fret and the middle finger to fret the D string’s second fret; when transitioning between these chords, keep those fingers stationary and only move your ring finger to the new position. Other examples of this include using the ring finger to fret the A string’s third fret for both C and F, and also using the ring finger to fret the B string’s third fret for both D and G. Using the common finger as a base while you move your other fingers will help you transition quickly and easily.
Many times there is no finger that is kept stationary between chord transitions and the whole hand must be moved. If the chord shape is relatively simple, you will probably be able to transition to it fairly easily. However, it is often helpful for more difficult chord shapes to fret one or two fingers first and then adjust the rest of your hand to complete the chord shape. This often means putting your pinky and/or ring fingers down first as an anchor and then moving your middle and index fingers to their positions.
