G/C diatonic accordion keyboard layout push notes.

The international diatonic accordion, which has rows separated by a fourth, has a fast, comfortable, open fingering style and reduces the need for bellows reversals by duplicating notes on the draw and on the push. Great for Folk music in 2 or 3 major and 2 or 3 minor keys. Music becomes much more difficult or impossible when it is less closely related to the home keys of the instrument or when it is chromatic. Do not expect to play music of much complexity in a variety of musical keys with similar ease, even using a modified diatonic accordion that has a chromatic range.

If you like bisonoric accordions but want to play any kind of music in any key with similar ease and you are willing to learn new fingering patterns, you should think about getting an Atzarin instrument!
