Chromatic accordion

Another still:
 
What are the relative merits of the B- and C-systems?

Both systems were developed around the same time, and both try to maximize the use of fingers within button layout.
Both are good to use and it is a matter of cultural preference.

Making chords on both systems is ergonomically easier on your right hand than with a piano layout so if you are going to play complicated pieces like classical music.

However, finding a C system accordion in North America is easier than B since the later are more common in eastern European countries.
 
I’m in the Pacific NW USA and I’ve never encountered another CBA player since I picked it up almost exactly 2 years ago. It is definitely a commitment trying to find instruments. I do see boxes come up occasionally on craigslist or reverb, but ended up buying a used one up in Seattle from Petosa and then a couple others from Europe. It is a great conversation starter—after every gig I seem to have a 20 minute Q&A session with curious audience members.

It surprises folk to learn that the fingering on a CBA is less difficult than it is on a piano keyboard.
 
As I have discovered, hens' teeth and rockinghorse droppings are in more plentiful supply. :(

People who have them seem reluctant to part with them and/or play them into the ground.
The only reason I must have asked was because I think Frosini played a B system. However, I think I’m “cured” at this point. I still have enough “homework” for my present piano accordion(s).
 
I’m far from an expert, never having even touched a CBA. It occurred to me that a Roland CBA would be the ideal for someone who wasn’t sure which CBA system would suit them best, because it’s capable of providing six CBA treble systems in one instrument. Of course, I’d reason, the smallest and least expensive Roland, the FR-1xb, would be the one most beginners would want to try.

Then I came across a post on another forum from someone who began on PA, bought a Roland FR-1xb so that they could learn CBA and now wants to trade up to the FR-4xb because they “ran out of notes” …😉

FR1xb was my introduction to CBA for the reasons listed to see if I could make the switch. After a few weeks, I was convinced and traded my first PA toward a “real” acoustic CBA within a couple months. Shortly after I swapped my FR4x PA for a FR4xb. I hardly play either Roland these days, so maybe I should rent/loan them out to other players with similar curiosity.
 
Just to add confusion I will mention the Janko button system. It is basically a piano keyboard rendered as buttons. it has repeating rows to give alternate fingerings. I have one in the shop made by Weltmeister called the "logiccordion". https://en.wikipedia.org/wiki/Jankó_keyboard
