These resonators are finely tuned to allow your child to develop a keen ear for clear and accurate pitch.

Each person will need their own pair. If your child is under 9 months, it will be enough to get only 1 set.

If your child is older, they might need their own pair separate from yours, so they can explore while you model musical behavior with your own set.

PLEASE NOTE A D RESONATORS ARE HEAVY AND MIGHT REQUIRE EXTRA SHIPPING FEES.
