When you begin your journey on the instrument, it can be quite an exciting time. There is a whole new world that quite literally is available at your fingertips, and since some of the fundamental techniques place less emphasis on speed, they can become quite boring to practice. I can't even begin to tell you how many players I've encountered who can play fast, but not necessarily cleanly. This tells me that a bulk of their practice time was used to increase speed, and, as a consequence, their playing lacks clarity. I often think of music as a language, and the guitar as a means of communicating that language. Even if you have an expanded vocabulary, an impediment to your speech can confuse the message, or, in terms of the guitar, can make it less enjoyable for the listener. This is especially a shame, because music tends to be a language that transcends typical lingual and cultural (and even generational) barriers. It is for this reason that we will discuss muting, bending/vibrato, and playing dynamics - the trifecta of emotive guitar playing (which are often neglected by rock guitarists).
In our previous discussion, we covered the basics of chord construction, and I left you with the task of playing the major chords in the open position (CAGED chords). At this point, you should be able to switch between each of the open chord shapes with relative ease, if you still find some difficulty, it is still possible to continue on as we are going to cover each chord's parallel minor by changing one simple (and important) interval - the third.
In continuation of our previous discussion regarding chord construction, we will cover a simplified approach to what is known as the "CAGED System" At this point, you should have practiced each of the chord fingerings and switching between them. If you can't yet switch seamlessly between each shape, you may still continue on, as this discussion will cover the vices and virtues of the CAGED system.
