How to do pitch accents in Ancient Greek

The presenter seems to have a deep understanding of music and Ancient Greek and a neat perspective of growing up in China(tonal language) whilst speaking English at home.

After watching her video and nosing around her channel description, I see she does Koine, so Idk if that matters in this regard(pitch in Ancient Greek), as in, should I even try to understand her presentation :O?

Idk if this is a system that she has come up with herself or is she just explaining someone else’s theory as to how it may have worked. It’s all way above my head but still super interesting! I’ve been wanting to share and thinking some of our more experienced Ancient Greek members of the congregation may enjoy it and hopefully have some wisdom to share 💜
