I've always been amused at how many sources state the "tube with one end open" model, derive the "odd harmonics only" behavior from the model, and then never engage with the observable behavior of the instrument or reconcile it with the model.

I did find this when trying to understand that disparity, but I don't know enough to confirm/refute/amend the explanation:

Thank you! I did notice that "odd harmonics" thing but never connected the dots and realized I was contradicting the article.
