They that touch pitch

The ancients, I learn from the lecture, had no standard system of tuning. Wherever you went, the pitches you heard depended on the ears and traditions of the locals, and on whatever instruments they happened to have and how they were tuned — tuned to each other and not to some universal standard. Their music is probably unreproducible and lost to history. The universal standard of having everyone up to concert pitch is convenient, but the other way appeals to my imagination too. But then again, just about everything that smacks of local isolation appeals to my imagination.
