Good to see another player staring down the jazz path!

Now, if you're classically or even formally trained, you just need to get hold of a book and start learning those chords and strumming patterns. If you're not, like me, it's a bit more hit-and-miss. To find jazzy chords, I simply take a basic barre chord shape - major, minor, 7th or minor 7th - and just move the notes around a bit to see what sounds I can get. I also try them in different voicings and inversions. There are plenty of possibilities. That's the beauty of jazz - anything goes if you can make it sound cool!

As for strumming patterns, you just need to listen to a whole lot of jazz guitar. Make note of the most commonly used devices and practice them. Once you're familiar, you can begin using variations on them and/or create your own.

Don't know if my gibberish was of any help :o, but there you have it - jazz for the uneducated.
