I’ve started a new video series on my YouTube channel. The first part of an introduction to chords is there.

The major and minor chord charts shown in the video are available for download in the Free Titles section of the music catalog: www.jamesgilbertmusic.com/catalog.php
There are also some other chord related files there that will be applicable to future videos.
