Open Voiced Major Triads
Since major triads are built with 3 notes, it is possible to drop the second highest note (the middle note) of a major close voiced triad up an octave to produce what will call a drop 2 voicing referred to as open voiced triad.
It is a very much appreciated technique by composers and arrangers.
This concept can be applied to any chords as minor, major, diminished and augmented.
The chart below show you three major open voiced triads in connection with the three guitar diagrams below.

Let's take an example with a close C major chord.
It is built with a root (C), a third (E) and a fifth (G). By dropping the second highest note (E) up an octave, we obtain a new sequence of notes : C, G and E respectively the root, the fifth and the third.
This is a C major open voiced triad chord. Bar 1
In bar 2 the second highest note of the first inversion of C major is dropped up an octave. That gives E (third), C (root) and G (fifth), referred to as an open C major chord third in the bass (C/E).
As you can see in bar 3 , the second highest note of the second inversion of C major is dropped. Thus giving G (fifth), E (third) and C (root). This is a C major open voiced triad with the fifth in the bass. (C/G).
