Start with five notes
Place your right-hand thumb on C and your other fingers on D, E, F, and G. Play up and back down slowly. Give each note enough time to sound clearly.
Listen for an even sound
Notice whether one finger plays much louder or arrives late. Repeat the pattern at a pace where every note feels easy to control. Let your wrist move naturally instead of holding it rigid.
Try the other hand
Use the left hand on the same five keys, beginning with the little finger on C. Work with each hand separately before you try them together.
