How it works
Hear the chord, tap its color
-
1
Tonmi plays a chord
A real piano recording, one color at a time. The flags come down while your child listens.
-
2
Your child taps a flag
The flags pop up as soon as the chord sounds. Big, friendly, and touchable from the first moment.

Balloons!
Every right answer brings balloons to pop right away. Every session ends with confetti and a sticker to choose.
That is the whole game — no reading, no menus, no wrong-answer buzzers. Just listening, tapping, and a lot of balloons.


The method
The Eguchi method, from Japan
Some children grow up hearing music the way the rest of us hear words. That ability — knowing a note the moment it sounds — is called absolute pitch, and research suggests it can be trained in early childhood, roughly between ages 2 and 6.
Tonmi follows the Eguchi method, where thousands of children have learned to name chords this way: one color at a time, a few short sessions a day, over months of gentle repetition. In a published longitudinal study of the method, every child who completed the training developed absolute pitch.
