Which part is holding you back?

  1. Chords & inversions feel intimidating?

    Recognize and play any chord — major, minor, sevenths and beyond — in every inversion, until it's automatic.

  2. Scales & key signatures won't stick?

    Drill the diatonic chords and scales of all 12 keys, so you instantly know what you're seeing and where your hands go.

  3. Reading note by note?

    Turn on staff mode and learn to read whole chord shapes and patterns in the key.

  4. Can't tell chords by ear?

    Ear-training drills build the pitch and chord recognition that lessons rarely have time for.

  5. Practice fizzles out?

    Daily streaks, levels, hearts and (yes) LOL-cat rewards keep you coming back.
