Guess the Sound

这个游戏是做什么的？

孩子听一个音，再从选项中选择对应的音名。游戏的目标是帮助孩子建立“听到的声音”和“音名”之间的直接联想。它是一个长期练习工具，不是考试，也不保证一定获得完整的绝对音高。

怎么和孩子一起玩？

• 点击 Start 开始一轮游戏。
• 音频播放后，让孩子选择听到的音。
• 孩子可以点击选项，也可以按键盘数字键（例如 1、2）选择答案。
• 答案页会显示正确音名和 emoji；按 Enter 可以继续下一题。
• 答对会有礼花和庆祝音效；答错会再次播放正确音。
• 如果孩子中途不想继续，可以点击右上角的小型 End Session 按钮；未完成的一轮不会计入 session。
• 一轮默认 10 题。建议短时间、低压力地玩，不要和家长比较输赢。

像 C4 这样的名字是什么意思？

C4 表示音名是 C，位于第 4 个八度。C3、C4、C5 都是 C，但音高不同；G4 表示第 4 个八度的 G。这些不是 C 大调、G 大调，也不是和弦名称。当前游戏主要训练白键，并逐步扩展到 C3–B5。

Settings 可以设置什么？

• Save practice records：是否保存每道题的详细数据。
• Volume：调整播放音量。
• Celebration sound：开启或关闭答对音效。
• Current Level：家长手动选择难度。
• Good Rounds Needed 和 Accuracy Needed：设置升级条件。
• Player Style：切换 Girl/Boy 主题和 emoji。
• Achievements：查看练习天数和完成 session 数。
• Export CSV / Export Progress：备份数据。

Level 如何增加？

每个新 level 只增加一个新的 note，难度会慢慢上升。当前默认规则是：一轮 10 题，正确率达到 90% 算作合格；连续 2 个合格 round 后，才进入下一个 level。家长可以在 Settings 中调整 Good Rounds Needed、Accuracy Needed，也可以手动选择 Current Level。

如何记录和分析练习？

打开 Save practice records 后，程序会记录每一轮、每一道题的目标音、孩子的答案、是否正确、反应时间和当时的 level。家长可以在 Settings 中点击 Export CSV 下载数据，再用 Numbers 或 Excel 自行分析准确率、反应时间和长期变化。

成就和记录

完整完成一轮才算一个 session；同一天完成多轮只计一个 Practice Day。关闭详细记录时，成就仍然继续累计。CSV 记录用于家长长期分析，不是对孩子评分。

What is this game for?

Your child listens to one note and chooses the matching note name. The goal is to build a direct connection between a heard sound and its label. This is a long-term practice tool, not a test, and it does not guarantee complete absolute pitch.

How should I play with my child?

• Click Start to begin a round.
• After the sound plays, let your child choose the note they heard.
• Your child can click an option or press its keyboard number, such as 1 or 2.
• The answer page shows the correct note name and emoji; press Enter to continue to the next question.
• A correct answer brings a celebration; an incorrect answer plays the correct note again.
• If your child wants to stop, click the small End Session button in the upper-right corner; an unfinished round is not counted as a completed session.
• A round has 10 questions by default. Keep practice short and relaxed, without comparing the child with a parent.

What does a name such as C4 mean?

C4 means the note name is C and its register is octave 4. C3, C4, and C5 are all C notes at different heights. G4 is G in octave 4. These are note names, not keys such as C major and not chord names. The game currently focuses on white-key notes and gradually expands from C3 to B5.

What can I change in Settings?

• Save practice records: whether each question is saved for later analysis.
• Volume: playback loudness.
• Celebration sound: the sound played after a correct answer.
• Current Level: manually choose the difficulty.
• Good Rounds Needed and Accuracy Needed: define the upgrade rule.
• Player Style: switch the Girl/Boy colors and emoji.
• Achievements: view practice days and completed sessions.
• Export CSV / Export Progress: make backups.

How does the level increase?

Each new level adds only one new note, so the difficulty rises gradually. The current default is 10 questions per round; at least 90% accuracy makes a qualifying round; two qualifying rounds in a row unlock the next level. Parents can change Good Rounds Needed and Accuracy Needed in Settings, or choose a Current Level manually.

How can I record and analyze practice?

When Save practice records is on, the game records each round and each question: the target note, the child’s answer, correctness, response time, and active level. In Settings, click Export CSV to download the data and analyze accuracy, response time, and long-term changes in Numbers or Excel.

Achievements and records

A session is counted only after the whole round is completed. Multiple rounds on the same calendar day count as one Practice Day. Achievements still increase when detailed record saving is off. CSV records are for a parent’s long-term review, not for grading the child.
