Movable chord shapes
By learning movable shapes, you will instantly know all chords in a particular category. For example, if you learn the shape for the A9 chord you will automatically know A#/Bb9, B9, C9 and all others in the same chord family. That is because you only have to move the same chord shape up or down the fretboard.
One of the advantages of movable chords is when it comes to more uncommon chord categories that you don’t use very often. In these cases it is an advantage if you only need to memorize one single chord shape.
F-shapes: major, sus, 6th and add
The major F chord that includes four fingers are movable, and, with adding a finger on different strings three additional movable chords could be played.
The shapes above are major, sus4, 6th and add9. Some examples with short notation:
The 6th chord includes four notes, a major and an added sixth. For example, C6 consist of C, E, G and A. You can use the chord shape below to play the 6th chord in all twelve notes. The root note is the same as the bass note.
As you can see the fifth and the highest strings should not be played. An easy way to mute the fifth string is to touch it with your index finger. Since the root is on the sixth string, you find G6 on the third fret, A6 on the fifth fret and then the rest with the same method. See the fretboard overview if needed.
Here is another relative uncommon chord that you can learn by only memorizing one movable shape.
The 9th chord consists of five notes and is built by adding the ninth to a dominant chord. The C9, for example, includes the following notes: C, E, G, Bb and D. The root is on the fifth string.
The 11th chord share some features with the 9th chord shape. This chord consists of six notes, but in the shape below only four are used. There are more ways to play this chord, but it isn't necessary to play all notes in the chord. The notes in the chord are the root (6th string), the third, the minor seventh and the eleventh.
The 13th chord consists of seven notes! So it is impossible to play all notes simultaneously on a six-stringed guitar. Instead, we choose the most important notes and this result in many variations of how the chord could be played, even among movable chords there are many variations. If one movable shape could be called standard, it would be this one:
The root is on the sixth string. For example, G13 with short notation is written 3X345X.
The seventh sus chord is relatively uncommon and for some notes the shapes are pretty hard. Therefore, a movable alternative could be helpful. The root note is on the fourth string.
Alternative major shapes
There are lots of other ways to play major chord besides the open and bar chords.
This could be used for nice fingerpicking and some examples of chords are:
Notice that you should also play this shape with an open A-string when in A major key. In that case three central chords are:
A: X0 11 9 10 X
Voicings with open A major shape:
Sometimes it is easy to play guitar and doing something new. Here are two chord voicing based on the common A-shape, major and sus4 (plus a third variant, see above). Move around the shapes and vary between major, sus and the third shape and you chould, for example, play in a Keith Richards-like style.
