~ D, Cadd9, G chord progression ~
Here are the chords that we're going to use
Let’s look at how to change chords easily. Notice when changing from D to Cadd9, the 3rd finger can remain where it is. This is a pivot finger. Leave the third finger still when changing between these two chords. Between Cadd9 and G, the 3rd finger may remain still again. Use this pivot finger when changing chords. When going back to D, again the 3rd finger is the pivot finger. During this whole chord progression, the 3rd finger never has to move. This will help smooth out the chord progression and cut down on mistakes. Let’s learn a strum pattern for this chord progression. Try "Down Down Up Down Down". First let’s try this on the D chord.
Now let’s try changing chords. The whole chord progression will be D Cadd9 G D, then start over again with the D chord.
