Here’s a jazzy sounding 2/5 turnaround I find myself using more and more to tickle ears with. For this example we’re in the key of Eb major so Fm7 and Bb7 are the 2/5 chords. The 2 chord is a normal minor 7 but I’m adding some interesting embellishments to the 5 chord as you can see, making it a 13 flat 9 instead of a plain old dominant 7. The reason for doing that will soon become apparent.

Here they are on the top four strings.

Fm7
E) - - - - - - - x - - - - - - - C
B) - - - - - - - - x - - - - - - Ab
G) - - - - - - - x - - - - - - - Eb
D) - - - - - x - - - - - - - - - Ab
A) - - - - - - - - - - - - - - - mute
E) - - - - - - - - - - - - - - - mute

Bb13b9
E) - - - - - - x - - - - - - - - B
B) - - - - - - - x - - - - - - - G
G) - - - - - - x - - - - - - - - D
D) - - - - - x - - - - - - - - - Ab
A) - - - - - - - - - - - - - - - mute
E) - - - - - - - - - - - - - - - mute

Here they are on the inner four strings:

Fm7
E) - - - - - - - - - - - - - - - mute
B) - - - - - - - - - - - - x - - C
G) - - - - - - - - - - - - x - - Ab
D) - - - - - - - - - - - - x - - Eb
A) - - - - - - - - - - x - - - - Ab
E) - - - - - - - - - - - - - - - mute

Bb13b9
E) - - - - - - - - - - - - - - - mute
B) - - - - - - - - - - - x - - - B
G) - - - - - - - - - - - x - - - G
D) - - - - - - - - - - - x - - - D
A) - - - - - - - - - - x - - - - Ab
E) - - - - - - - - - - - - - - - mute

For me the voicings on the inner four strings are a little easier to hold than the voicings on the top four strings. The inner four strings also have a better tone IMO.

The neat sound is the voice movement from one to the other. There are three notes in each chord that move down a half step while anchoring the whole thing with the Ab note (which changes from being the minor 3 in the 2 chord to being the 7 in the 5 chord.) I use this in songs like “There Will Never Be Another You” to great effect for the turnaround.
