Store description excerpt
Young children can acquire absolute (perfect) pitch — but adults cannot. The window closes around age 6. BSharp helps your child develop this ability using Eguchi's chord identification method, a research-backed approach for children aged 3–6. HOW IT WORKS Children listen to piano chords and learn to identify each one by its color. Start with two chords (red and yellow) and gradually introduce new ones as your child masters each level. Practice 5 times a day for 2–3 minutes each session — about 20–25 identifications. FEATURES • 14 chords across 9 levels of white-key chords and 5 levels of black-key chords • Adaptive practice that focuses on chords your child finds difficult • Session statistics and history to track progress over time • Multiple profiles so siblings can each have their own progress • Trainer mode to preview what each chord sounds like • Chord note display with geometric shapes and letter names • Dark and light themes • No ads, no account required • Works completely offline ABOUT THE METHOD Eguchi's chord identification method was documented in research published in Psychology of Music. Children associate chords with colors (red, yellow, blue, black, green, orange, purple, pink, brown) and progress through levels. New chords should be introduced no sooner than every 2 weeks, and only after the child can identify all current chords with 100% accuracy. Based on the open-source CIM Trainer by Paul Ganssle.
