E Chord Form Basic Mods
Basic mods include EMaj7, E7, Em7, Em, Eadd9.
In the E form session, we learned to bar with our index. In this session series, we will work with the A Form, which has the 3 (or 4) finger barring. Like all of the forms, it is also commonly broken down into other usable pieces.
To get into the shape, we can play the A chord in the way it will be moved: lay the index over the nut, with the tip on string 5. Then bar the 2 fret with the 3 finger [pinky can work too]. We don't have to do this, but it helps us see/feel/know the shape that is movable.
Once we get into a shape, it can be shifted to every position. 12 things, for knowing 1 thing, is good mileage.
When moved, the bar part of this shape can pose a challenge [typically with 3 finger, but the pinky can work]. If challenging, we should keep working at it, even when there are 'bar-less' ways to play this form [see mods/breakdowns below].
We often see this chord in other sources with the high E open on the A chord, and this is fine and can be included. Yet, the inside 4 strings do ring in a particularly resonant way, which sounds good and is slightly easier, on the fly. Also, when it's moved, that same tone on the 1 string [the 5th of the chord] can be included under a bar fretted by the 1, and the 'previously barred' tones would then be fretted with the 2-3-4 fingers on the 4-3-2 strings [not really that easy].
The E minor Pentatonic/G Major Pentatonic [E-G-A-B-D] is a 5 tone scale. Music which is key-based typically uses scales with 7 [heptatonic]. So, let's add two [using scale starting from the E in a general sense]...
An example: at fret 5 for an A form, the index will be at a D tone, so the chord will be D Major. Every flat name has a sharp equivalent [enharmonic, same thing, different name]: A flat = G sharp, B flat = A sharp, D flat = C sharp, E flat = D sharp, G flat = F sharp. Yet, for Major type chords, all of them are typically flat names except G flat/F sharp, where both are used.
