Funnels and Hats

You are looking at a single chord shape as it is arrayed across the fretboard.

The interval structure of these voicings is shown below:

The shape can be rotated 180º to form two voicings of minor 7th and major7th chords

as well as one voicing of dominant 7th and one voicing of a minor(major7th) chord.

The chords on the four top strings are all minor 7ths.

The chords on the bottom four strings are all major 7ths.

The chord in the middle four strings is a dominant 7th.

All these forms of the shape can, of course, be moved to any fret position and retain their interval structure, however, certain keys allow open strings to be added and so the funnel/hat form can be treated as both open and moveable chords. 

Next you can see all of the Funnels. Try playing them in this order using the Roman numeral Root notes a a guide:

VI - V - IV - II - V - I - III ...

Here's notation for the pattern:
