Common progressions in 5 easy keys

The twelve bar blues is made up of a repeating 12 bars structure. The song “Kansas City” works for these chords
(Note: Bars 1,3,4,7,8 and 11 are the “I” chord “one chord”) Six bars out of twelve are the “one” chord. That’s 24 beats out of 48 beats. Getting a feel for the progression is getting the beat correctly. 4 beats per bar.
