The Amazing Differentiated Group App

You just started violin but your buddy is playing the Bach Double. What do you do? Find music for both of you on this app. Theres only 1 song (4 excerpts) currently but there will be 28 this summer (2021). Did you master the red belt (open strings) but it turns out your buddy isnt ready for the silver medal? You can move to orange and your buddy can move back a few belts to get his bearings. "Well shucks Mr. Yoder, thats amazing." It sure is.NOTE: MAKE SURE YOU ARE IN FULL SCREEN OR YOU MAY NOT SEE EVERYTHING AND DECIDE IT DOESNT WORK.
