We previously moved a fragment of this chord shape. Now, we are going to build a full version = add the 3-2-1 strings. The chord components (R-3-5) are included. We get to memorizing these, as they are the basis for modifications (mods). To play this full version, we will use a bar [barre]. In guitar fingerings, when we fret the same fret, on different strings, at the same time, this is a bar. Like the word 'fret', 'bar' is a noun and a verb [and means other musical things - see notation and 12 bar]. When we bar, we can press the whole fret space, or only some strings. We don't have to press all 6 strings. Every chord, especially a bar type, has a hand shape [angle, points of pressure]. Any bar can be a hinge bar [I believe all bars are]. Hinge bars are toggling tones within a bar. More on this later. For this chord, we press the tip of the 1 on the 6 string, used a curved finger, and press just the 2 and 1 strings with the middle knuckle. This conserves hand power. To get into this bar shape, we can lay our 1 finger across the nut [using 3, 4, and 2 fingers fretting 5, 4, and 3 strings respectively for fretted tones] as it will cover all the stings once we move it [this will be barring]. We don't have to do this ['bar the nut'], but it definitely shows us how this chord is structured, and gives us a movable fingering.
