ChorusPals
Sing-along karaoke in YOUR key (ages 6–8): every song is rendered in the singer's own range so a young singer can always reach the notes (the Child-Key Rule). Read the words as you sing (lyrics first), and pass the mic — the same song moves into the next singer's voice. A buddy voice sings with you and gently fades as you get steady. No score, no autotune. On-device — your singing never leaves the device, nothing is recorded.

Meet the cast
ChorusPals' younger hero-anchored cast (ages 6–8): hero Chirpy the singing bird (the buddy voice that fades as you get steady) + a few gentle friends, no trauma depth (R-YOUNGER-CLUSTER-CAST-SIZE). Each friend embodies one gentle primitive (R-DN-PARITY). Illustrated portraits + DN-S chapters are on the way (STORY-PEND).
Chirpy
(Hero) sings along, then fades as you get steady and sure (duet-fade on confidence, embodied)
