Trikitixa or Basque diatonic accordion

The Trikitixa or Trikitrixa, is the popular Basque name for a type of international diatonic accordion that is used in the Basque Country. As such, it has rows separated by a fourth and a fast, comfortable, open fingering style and it reduces the need for bellows reversals by duplicating notes on the draw and on the push.

Although great for Folk music in 2 major and 2 minor keys, music becomes much more difficult or impossible when it is less closely related to the home keys of the instrument or chromatic. Do not expect to play music of much complexity in a variety of musical keys with similar ease using a Trikitixa!

If you like bisonoric accordions but want to play any kind of music in any key with similar ease, much better chording, much smoother, easier bellows work with less reversals, and you are willing to learn new fingering patterns, you should think about getting an Atzarin instrument!
