Where can I find Blues Chords?

well if you know your scales then number them and play your 1 4 5

Example (A) scale A-1 B-2 C# -3 D – 4 E – 5 F# – 6 G# – 7 A – 8

Now your 1 4 5 would be A D E so here we go

AAAA AAAA DDDD AAAA AAAD DDEE AAAA AAAA DDDD AAAA AAAD DDEE EEDD AAAA repeat until you cry
