Piano is just 300 years old? There's more.

Great post, @richardbrand .

btw I had posted that Haydn wrote baryton trios

Veena, a Indian stringed instrument has ~4000 years of documented history. , i.e fairly complex build, metallurgy required.

"Simpler" wind instruments go ways back... For example, the didgeridoo (indigenous instrument of Terra Australis) goes back at least 20,000 years.

I love classical and jazz piano and factory tours! Here is a sample of piano factory tour documentaries available on YouTube (in alphabetical order but couldn't controll font sizes). All are fascinating and promise to bring new appreciation:
