Problem

Playing with both hands and chords is the next major hurdle for those who have outgrown simple melodies. Users want to learn full songs just as easily, but existing tools either lean toward academic training or oversimplify without real progress. A quick visual way to show two‑hand playing still does not exist.

  • Sheet music requires skills that intermediate players often lack
  • Video tutorials offer no control over tempo or step‑by‑step progression
  • Most apps offer uninteresting repertoire
  • Interfaces are either overly academic or game‑style, with no middle ground
