Six Unison Melodies
Study the first module (exercises 1-9) focusing on perfect hand symmetry. The sound should come out simultaneously; the hands should hold a rounded shape, playing with a soft and natural gesture.
Don't worry about the speed of performance, only about the quality of sound. When you have studied exercises 1-9 well at a slow tempo, start over and try to play them at a slightly faster tempo.
