You don't have to stick to play just these chords but you can mix them up and of course you can play larger chords. If you can play this simple stuff you can hold down a basic shout at your church. I mixed up some of the sharps and flats.

I partly did not post them correctly because I know it will get confusing to those of you who are beginners. Theory lovers please forgive me.

One thing I try to do when playing chords is use all of my fingers to play faster and for finger strength. Also I do this to find the most convenient way of playing my chords. If you don't use all of your fingers on your hands get used to doing it it will help you in the long run.

Example of using all my fingers. T-1, I-2, M-3, R-4, P-5
In C
/CEbG......1,2,4
/DFA........1,3,5
/EbGBb.....2,4,5

I would maybe play something like that or I will play like this.
/CEbG......1,2,3
/DFA........1,2,5
/EbGBb.....2,3,4

Just try what ever is comfortable to you but if you work on using all your fingers you will find out later that it will help you in chording with both hands, playing scales, and playing larger chords.

I will modify this post and post some midis later. Also if you would like to know what fingering I use in the shout bass just let me know and I will post it.
