If I understand correctly from your post, it points out that chord inversions and chord voicings have different properties.
In other words; an (A-E-G-C#) cannot qualify as a Chord Inversion because it skips notes and only the sequence of notes can be altered for an inversion.
But (A-E-G-C#) can qualify as a Chord Voicing because it allows for notes to be skipped or repeated and still remains a voicing of A7.
Would this be a correct statement?????????
