Not much of a musician in the slightest but scales and integer notation solve that.
I think 12 scales, major and minor each have 12 scales.
Can do most of them one handed but not with two hands so not sure what to advise.
3poly is 0-4-7
4poly is 0-4-7-11
0 as root note, follows semitone counting.
if going just by scale order then 1-3-5
1 is first note of scale. Scale counting.
Recently I've decided to hiatus for a few to study up on those more, and I shit you not...you can find any chords by getting comfortable with stuff like that period.
By default every chord ever. 12 major and minor scales.
