Dominant seventh shapes7

It sounds restless and pointed at something. The V of a key, and the whole vocabulary of the blues, where even the tonic is one of these.

25 moveable shapes, 3 of them drop 2. None has an open string in it, so each one plays every root there is; the dots are degrees, and R is the root.

One shape, twelve chords

Pick a root and every diagram below moves to it. Nothing about any of the shapes changes — only the fret they start on, and each one starts somewhere different because they are rooted on different strings.

Showing C7. Every voicing of it, open strings included, is on its own chord page.

Root on the low E string

The lowest root available, so these are the fullest-sounding shapes and the ones that carry a band. F at the first fret, G at the third, A at the fifth: the shape is the same and the fret is the whole of the difference.

Root on the A string

The other half of the pair. Pair them with the low E shapes and the hand barely moves: the root a fourth up sits at the same fret on the A string, and the root a fifth up two frets higher.

Root on the D string

No bass note under it, which is the point rather than a shortcoming: these sit above a bass player instead of competing with one, and they reach the extensions the lower shapes have no fingers left for.

Inversions

The same chord with something other than the root underneath. You reach for one of these because of what the bass is doing, not because of what the chord is — a bass line that walks while the harmony stays put is made of these.

Drop 2

Close position — R–3–5–7 and its rotations — puts four notes inside an octave, which will not fit under a hand on adjacent strings. Drop the second voice from the top down an octave and it does. That is the whole operation, and it is why these exist: four notes, four adjacent strings, no gap to reach over, and the shape slides.

The base voicing only, one per string set. The same drop applied to the chord's other close voicings gives more shapes, but those are inversions of a drop 2 rather than of the chord, and that is a distinction worth more than it costs to explain.
