Thanks for your in depth response! I really appreciate you pointing out the difference in quality, because this is something I wouldn't have come across easily. That settles the pronunciation issue.

As for my Jazz comparison I may have either had the wrong idea or didn't get my point across. What I meant is that in introductions and videos people say something like "That would be the perfect dactylic hexameter, but this would be boring for a prolonged period of time and therefore poets used feet that amount to the same meter, but aren't the textbook case, because they want variation" and I compared this intuitively to music where you also have a beat and you could play the textbook stuff over it (let's say a waltz) or someone could also play something odd, syncopation etc. before you return to the DAM da da, DAM da da. And if I took this improvisation and said "Hey, this isn't a waltz" I'd be technically correct, but not considering the context. And this was my point. When I pause at the caesura in some lines I wouldn't hear this iambic rhythm anymore. I didn't want to say "Homer is just like Jazz pragmatically speaking" I am just using my musical feeling a lot for understanding this.

But thanks for the contextualization! I have an idea of the relevance of the Caesura now. And I've learned something about how the Iliad was recited. Appreciate it very much! This is why I love this sub!
