Fast and Comfortable Fingering

Natural and ergonomic fingering in which notes separated by a whole tone are found on diagonals and the fingers remain in their natural curved position, the index (pointer) finger on an outer row in relation to the fingers of greater vertical reach, namely the middle and ring fingers.

The use of the thumb is optional as Atzarin has been designed to be played without the thumb, an important consideration for musicians coming from other bisonoric instruments where the thumb is not used for playing notes. However, using the thumb greatly increases the ease and comfort of playing and makes it possible to use techniques that would otherwise be impossible, thereby increasing the expressiveness of the instrument.

Open keystroke/fingering style where the finger preparing to play the next note stays next to or moves away from the currently playing finger, but never under or over it.
