Other Open String Chords
We've already learned all the open position chords diatonic to C Major. Let's learn some common additional open position chords: E, A, and D major.
PreReqs
E Major
The E major chord consists of (E G♯ B). It is similar to the Em chord, but the m3 is raised to a M3 (G -> G♯). In open position, this is the open G string moving up to the first fret. If you remember the F major barre chord, this is the exact same shape, except we use the open strings instead of the barred index finger.

G♯ is non-diatonic to C Major. The E major chord is diatonic to the keys of A, E, and B Major; C♯, F, and G Minor; and A and G♯ Harmonic Minor.
A Major
The A major chord consists of (A C♯ E). It is similar to the Am chord, but with the m3 raised to a M3 (C -> C♯). In open position, the C is played on the 2nd string, 1st fret. A major uses the 2nd string, 2nd fret instead.

This is a particularly difficult chord to finger at first, and the best way to finger it depends from person to person. Some like to use index, middle, and ring for those 2nd fret notes. I find my fingers are slightly too big to do so comfortably; however, my middle, ring, and pinky fit with just enough clearance to sound the the nearby open E and A strings. Some also find it easier to barre those notes with their index or middle finger. I find my middle finger works ok for this method, but I have to angle it a bit, so that it takes up less distance from side to side of the fretboard, giving the high E string clearance to sound. But then I'm not using good fretting technique and the chord doesn't sound as good as when I use individual fingers for all 3 notes.
C♯ is non-diatonic to C Major. The A major chord is diatonic to the keys of A, D, and E Major; B, C♯, and F Minor; and C♯ and D Harmonic Minor.

Again, we sharp the third (F -> F♯) to go from Dm (diatonic to the key of C Major) to D major.
Homework
Practice the above chord shapes. These chords are all 4ths of each other and sound pretty decent played in a quick progression. Try playing E - A - D, then D - A - E. Really focus on the shapes of the root position chords - we will be using these shapes heavily later on.
