I think there is only one conclusion: we need an expansion which would explore instrumentation of Eora and it’s past and current advancement. What are th majors schools of music? What is the relationship between sacred and secular music? Is music education available to public (looking at the amount of “harpsichords” in low level taverns it seems so). Is music purely vocal (medieval and renesaince style) or is there a focus on an advanced instrumental works. Do major organised ensembles exist?
I mean, does anybody doubt that Sawyer would add this kind of detail to the TTRPG rules if Feargus would let him?

PLAYER: OK, I've leveled up my Woodwind proficiency enough that I think I'm ready to challenge the First Chair for his soulbound Chalumeau.
GM: Sure. You inform the Director, and he schedules a blind audition in two days. You'll have to select an exhibition piece to perform.
PLAYER: Ooh, is one of those hornpipes that we found in the Xaurip camp of an appropriate difficulty? Director Viretti is such a sucker for Wilder exoticism.
GM: Hmm. You think so, but you'll have to transpose the notation and make copies for the panel beforehand. Give me rolls against your Melodic Theory and Culture: Ixamitl Xaurip skills.
