上面是五线谱,下面是琴键。按琴键,音符落到谱上——弹过的音会排成一小段你自己的曲子,可以回放。横屏时琴键会变成三个八度,谱面也更长。在 ☰ 设置里可以打开「🥁 节奏模式」:你弹的音会按一个随机的 4/4 节奏型排队,实心是一拍、空心是两拍、还有八分音符、附点和休止符,回放时就能听到节奏了;难度也可以在设置里选。设置里的模式开关还有一档「🎵 弹曲子」:整首儿歌的旋律直接写在谱上,下一个要弹的音后面有一道金色光带、符头也更大,对应的琴键上有一个金点,按对了提示就往前走一个;按错只是发个声,提示留在原处,不扣分。换一首歌不用回设置——谱子上方的 ‹ › 就能换,按键盘的左右方向键也可以。回放的时候琴键会暂时按不动,▶ 会变成 ⏹,按它就停。
A staff on top, piano keys below. Press a key and a note lands on the staff — everything you play lines up into a little tune you can play back. Rotate to landscape for three octaves and a longer staff. In ☰ settings you can turn on "🥁 rhythm mode": your notes line up to a random 4/4 pattern — filled heads are one beat, hollow ones are two, plus eighth notes, dots and rests — hear it when you replay. The difficulty is in settings too. The mode switch in settings also has "🎵 play a song": a whole nursery rhyme is written out on the staff, the note you owe next sits in a gold band with a bigger head and a gold dot marks its key, and playing it moves the cue on. A wrong key just sounds — the cue waits, nothing is scored. Change song from the page itself: the ‹ › buttons above the staff, or the left/right arrow keys. While anything is playing back the keys go quiet and ▶ turns into ⏹.
