Regarding the classification of a new instrument in an instrument family, one can point to a number of fundamental issues, one of the most obvious of which is the instrument’s visual features. If we look at how the new instrument has changed compared to its historical versions, the set of visual elements that link the instrument to the Qeychak family becomes apparent.
