The difficult thing about guitar chords is not constructing and remembering them. It’s changing chords that is actually complicated. Chords have to be changed fast and with precision, all fingers moving simultaneously towards their new place while changing chords. You know it anyway. But how to achieve that? Let’s start with these two chords:
The first and the second finger don’t have to move when changing these chords, only the third finger has to change its place.
2. If you manage, play the chord already for two beats and leave two pauses for the changing:
3. Once you are changing smoothly and precisely, further reduce the number of pauses. Now you will be playing already for three beats and there is only one pause left for changing chords:
Important: If it is possible to leave some finger in the same place when changing chords, it must definitely be done!
