No, not for that age. Most music and instrument teachers don't want to teach reading music to kids until they are at least 5 and reading, so you would need to hear from the ones who do teach preschoolers. my kids started reading music and piano lessons in first grade and it worked well for them. They had a piano teacher though, we helped but were not teaching on our own.

Anyone has book/cd recommendations or online resources for 4 year old to learn how to read music notes, chords, notes something like that? I want kid friendly.
