Moveable Chord Concept


Rather than learn 12 (or more) variations for each chord type, one for each of twelve tones, it is for efficient to learn shapes on the fretboard that can be moved to create the required chord at hand. By not using open strings the guitarist can play shapes corresponding to a chord, based at a certain location corresponding to a root note, and create any chord he wishes and the other 11 by merely moving the shape up or down the fretboard.

Consider the E major and F major chords, they use the same shape but in the F, the open notes have become fretted notes, and now the whole shape is moveable able to produce the 12 major chords depending on which fret the note on the 6th string lines up with.
  E Major chord			  F major chord
R|---|---|---|			 |-R-|---|---|1
O|---|---|---|			 |-O-|---|---|1
 |-O-|---|---|1			 |---|-O-|---|2
 |---|-R-|---|3			 |---|---|-R-|4
 |---|-O-|---|2			 |---|---|-O-|3
R|---|---|---|			 |-R-|---|---|1

Notice that the fingering for the open chord (E) and the moveable chord (F) are different. Depending on the shape this may or may not be the case. The above shape, with root notes on the 6th, 4th, and 1st string, we will call the E-shape. We line up the 6th string root note with the note we want the chord to have as it's root note.

It's worth noting that the shape above can be carved up into smaller shapes, that are also moveable. For more information, look into chord voicings (see http://simianmoon.com/snglstringtheory/archive/aug23.html)
