Trail guide
Pitch Trail follows Eguchi's Chord Identification method: listen, choose the matching color, and add new chords gradually. See also the Ichionkai Perfect Pitch Program.
Designed for children aged 2–6. Pitch Trail is adapted from the open-source BSharp trainer and CIM Trainer. It is educational practice software, not a medical or developmental guarantee.
