The visible learning paths break subjects into numbered steps, with topics ranging from basic notes and rests to group ostinatos and multi-group percussion. The page also describes a “Mr. JJ” figure that responds alongside the learner, and says the instruments can be controlled by clicking or by pressing keys A through H. The listed songbook includes pieces marked by instrument and difficulty.
