Built for the song you chose. Everything here works with sound, so you can practise the shapes anywhere, even without your piano.
Every one of them lives entirely on white keys. Tap a chord, hear it, then tap the lit keys one by one to feel the shape under your fingers.
Your sheet writes minor chords with a dash instead of an m. They mean exactly the same thing:
The little 7 after D-7 adds one extra colour note. In the early lines we keep it as plain Dm to make life easy, and in the grand finale you get to play the real Dm7, which is simply Dm plus one more C on top.
Home base. The song begins here and always finds its way back.
