I'm wondering if I should use multiple versions of the same pitch to spell chords correctly even in the same key. Kinda weird.
I realise that's a typo, and you meant, if D G C F B is one chain, then G C F B E can form the other. Yes, that's correct. You always have a pai/pao chain and a plain chain. I don't know whether you should use both pai and pao spellings of the same pitch in the same key. I agree it's kinda weird. Maybe it's another of those cases where you should feel free to do so while composing, but should choose one spelling for each pitch if you're presenting it to others.
But I think it's fine, even when presenting to others, to use pai-spelling at one end of the chain and pao-spelling at the other.
e.g. D G C F B and A D F B E. And then maybe only the middle pitch F will sometimes change spelling to G.
But you're the pioneer here. Let us know what works for you.
