I've just started playing accordion 2 months ago, made good progress on a bayan (B-system). I am a professional pianist, and the reason I chose a button accordion is for the challenge, but also because I believe the keyboard layout will allow me to do things beyond what I could ever do with a piano keyboard (especially when it comes to improvised music).
Got myself a Roland MIDI accordion, which can be configured to play with the B or C griff.
I guess the main goal of playing the accordion is to play musette, but I am also into russian music, tango, paso doble.
So my big question is: should I
- stick to B-system
- switch to C as soon as possible
- try to learn both and switch depending on the kind of music style.
All infos on the internet explain that it's very 'personal', and also that it depends on the type of music I am going to play. However, I don't understand what the pros and cons are of each system, except that I read that the C system looks more like a piano keyboard, and the B has the advantage of letting the thumb be more active. Someone also told me that the C system is used in musette because it's more adequate for very fast pieces. But all that seems insufficient info to decide what's best.
I also thought of asking my teacher, but I expect him to be biased because he is a bayan player and may not even be able to teach me the C-system?
