One day you gonna learn to start with the bass, LOL. Anyways, what you need to do is get a pattern for you chords. I'm familiar with this song, and here is a basic bass pattern that will help. Try it and let me know how it goes:
1
He's sweet I know,4
He's sweet I know,1
dark clouds may rise,2
stormy winds may5
blow,1
I'll tell the world where-4
ever I go, that1
I3
found a6
Saviour, and2
He's5
sweet I1
know,5
(repeat)
Remember, most songs (gospel or any other genre) stick to the the (7)-3-6-2-5-1-(4) pattern. There are songs out there that break the mold temporarily, but eventually get back to somewhere in this pattern.
You don't have to play a chord for every word. Most words don't need a chord, just find the main ones and then you will see your pattern. The melody notes give you clues to the chords u need, but the bass solidifies it.
Keep practicing SisterCM, ur doing great!
