Mari's Wedding is in ternary form and is a modern jig. 6/8 time and in D minor.
There is nothing more complicated than crotchets and quavers throughout-hence I anticipate a competent intermediate player will be fine with it. I have not included bowing marks as I have left it to the individual player. The influence is Scottish/Irish/Celtic/Folk
