I saw a CH-47, which is unusual enough that I had to snap a pic:

There are a couple parts of the court music book Orchésographie that I think would be particularly interesting for a bard character.

Court musicians in the late 16th century frequently traveled to where the work was: either following a particular patron or looking to perform where they could. Most of the dances in the book are bransles, a folk dance popular with the “common people,” and formalized when brought to court. As a D&D bard, this would be a cool way to explain why your music is beloved by all, and why they could move in all social circles.

There’s also a part at the beginning that explains how to play the drum and fife for a marching army: how to improvise a melody or change up the drum pattern while keeping the march going. It seems to imply that the court musicians the book was written for were potentially marching with armies, likely playing music in the camps or stops at night.

We actually have quite a few troubadour “songbooks” from the late middle ages, indicating that it was a useful resource for minstrels of the time.

If we’re getting into the Renaissance period, a professional musician would almost certainly be able to read; we have printed music manuals from the period for all kinds of instruments; for example, Arbeau’s Orchésographie is a primer on courtly dance music that we still read today.

Your POV:

Cool, I’d hate to live in a place where you can creep on your neighbors.

I bet it’s a pervert’s dream.

You think so? You think you have a right to install your camera on public property?

There are usually peeping tom laws that prevent this kind of thing, and it’s certainly cause for a civil harassment case if the person you’re spying on knows about it.

The real question is: why do you want the ability to film someone’s house like that unless you’re a creeper?

Good news, there’s a vacuum leak.

Depends how old. If it’s a Shakespeare play, I like to have read the play beforehand so that I can understand the nuance in the performance. If it’s an opera, I’ll probably read a synopsis beforehand. If it’s a stage play in English written since the 19th century I’ll probably have more fun going in without prior knowledge.
