Hi
If the accordion has Stradella type basses (with basses and chords) they are normally a subset of the full 120 bass pattern – look at this picture and you can see that the most common 3 row design is not 21 but 24 bass but I don’t specifically know your Yamaha 21 bass – I would expect it to be the same as a 24 but with 3 buttons les at one or other end but it could also be a free bass system with no chords. I hope this helps! https://3.bp.blogspot.com/-niE6FT9sOmg/TntPS5epLJI/AAAAAAAAAQo/mKp4nMlDH4I/s1600/accordion04w.jpg
I am looking for bass 21-key pattern of Yamaha accordion, Japan.
Can you help me with a diagram?
