When I go out of town, I usually attend a local church. At one church, I heard a song with some nice jazzy changes so when I got home I worked out a close rendition on my guitar. This is what I came up with (p.s. - if anyone knows the song, please tell me)

First, here are the vanilla chords that I used as a skeleton...
( Ebm, Bbm ), ( Cb, Db )

Now the jazzier changes...
( Ebm7, Bbm7 ), ( Cbmaj7, Db, Bb/D )

Adn finally, the way I play it in case you want to try it yourself...

|----------------------------|
|-6h7--6--676-----7----6---6-|
|-6----6-----6----8----6---7-|
|-6h8--6---------8-----6---8-|
|-6------------------4---5---|
|------6-6------7--7---------|


My rhythm in the tab isn't exactly right... the 6, 7, 6 thing over the Bbm7 chord is a triplet, etc. Just play it until it sounds good to you. I noticed that the rhythm is different from most songs... The first chord of the first measure gets 3 8th counts, and the second chord gets 5 8ths. The first chord of the second measure gets 3 8ths, the second chord gets 2 8ths, and the 3rd chord gets 3 8ths. It's this ahead of the beat playing with the jazzy chords that makes it sound so good. Hope you like :)
