Inside the bandoneon
I can read music and I learnt the piano for many years. I am told it is amazingly complicated to play, with different notes on each of the two keyboards depending whether the bellows are out or in!
For some reason we started talking about the inside of the bandoneon... have you ever wondered what this amazing instrument looks like inside? So I checked it out on the internet and this is what I found... much more complicated than the inside of a piano!
