I'm struggling to understand how and why diatonic chords work and what their purpose is within played music.
To my understanding, diatonic chords are a triad on any degree, in any scale, where each triad note is 2 generic thirds apart.
If that's correct, it seems to fly in the face of how each scale defines chords. It seems like diatonic chords ruin the purpose of the established structure. I.E. why call it a major scale if we have a diminished chord in it. The diatonic chords can seem quite out of place.
What is the purpose/relevance of diatonic chords in music?
How/where they can be applied, I.E. what can be/has been done with them?
(Examples in written, visual, and/or audible fashion are very welcome. 😊)
[Edit] In review, the question was created out of a misunderstanding of what a generic 3rd was which gave the impression of diatonic triads being something different than your standard triad on a note from a diatonic scale.
Feeling very silly now understanding what a diatonic chord actually is...

Thanks again for all the help on what was a pretty obvious topic! 😁
