I am an early child development therapist and the author of a program for early childhood development through music, activities, and games. I am a developer of early solfeggio teaching material for a wide range of musical instruments aimed at children. Teachers or parents don't need any special education to use my learning method. Also, I offer sheet music books (paperbacks or e-books) with color-coded, letter-coded, and simplified musical notes for kids and adult beginners. Another of my fields of interest is folk and ethnic music.
