Create a free account so your pianist, progress, and high scores are saved — and follow you onto any device.
A MIDI keyboard makes this a real piano lesson. No cable handy? You can explore with the on-screen piano keys and connect your piano later — this guide is always in Settings → Connection guide.
Drag a piece variant onto a board to assign it — onto another chip to
take that chip's spot on the path. Level 1 (the starter zone) is five separate tutorial boards, so drag
between subzones to move a piece around the meadows.
Each chip's dropdown picks the rival who guards that space. auto keeps the old positional rule
(spaces 1-2 = first minion, 3-4 = second, last space = the boss); choosing a name pins that rival to the
piece instead, so one rival can guard several spaces and the boss need not be last. Moving a piece to
another board resets it to auto, since each board has its own rivals.
Tempo % is that variant's adjustment — the master base tempo lives in the note editor
(Settings → Manage pieces).
