Now let's try out the root-chord strumming in a song.
We'll start out the song with a little intro, where we strum the A minor chord as whole notes for 2 bars. Then we're into the main section of our song, and for that we'll do the root-chord strumming of our A minor chord for 2 bars, and then we'll switch to C major for 2 bars.
Next we'll go to D major. We'll do that for 4 bars, and that'll be our progression for the song. Now we'll repeat it once more, and when we transition back from the D chord, back to A minor we'll hit a strum of the open strings on beat 4 to help with the transition. It both sounds good and it makes it easier!
And finally we'll reuse our intro as the outro and then we'll just end the song on that second A minor strum.
