I have rudimentary knowledge of music theory. I mainly go by feel and improvise.
However, I have a feeling that the I IV V combo is very important. In other words, in the key of C, it would be C, F, G chords. But there are other useful combinations as swell.
Any consonant chords which sound resolute would work well (no excessive use of augmented, diminished, or minor chords). So always kind of sticking with the chords consisting of I, III, V notes (C, E, G in the key of C). That’s not to say you can’t deviate from this a little here and there.
There has been extensive talk about the different colors and moods of each key as well. I won’t go into that, but I used C as an example because that the most common and basic and easiest to use for examples.
Variation, creativity and ingenuity go a long way in coloring and flaring your music to make it sound unique, despite using similar chord progressions —there’s timing, tempo, style, orchestration, instrumentation, key used, key changes, use of silence, rhythms, and so and and so forth.
