I was watching this video: https://youtu.be/7ji0ppAJjMg?t=435
Context: Samsung has filed a patent for a "Z-fold" phone that folds in two places, rather than just one.
At 7:15 the host said:
"Samsung is the farthest along in this folding phone race, but at this rate it feels like we're only a couple of years off from the first accordion folding phone, which, according to its patents, will play you a Bavarian oom-pah tune."
I couldn't understand what he meant by "Bavarian oom-pah tune".
What I got so far from the internet are:
1.Bavaria is a place in Germany!
2.Oom-pah tune is some kind of a sound of a deep brass instruments!
It felt like he was trying to be sarcastic. But didn't get the idea. Why is it funny if a thing can play "Bavarian Oom-pah tune."
I want to know what actually is he trying to say and why did he use this particular phrase! And how can I use this phrase to make a sentence!
