Read the Staff, Name the Key

Notation that is drawn, not photographed

The theory wing is built on geometry. Staves, note positions, key signatures, time signatures, and note values are all rendered as pure line work — no scanned sheet music, no stock images anywhere. The instrument pages extend the same idea: eight open guitar chord diagrams and a keyboard octave, each drawn from scratch. Clefs are named in the question text instead of drawn, so what sits on the screen is exactly what the question is about.

Checked before it asks

Every drawn position was decoded and verified against theory by an independent review before a single question was generated — 59 items, zero disputes. The trivia hub went through a different filter: composers, orchestral families, and Italian terms were written twice, by two authors working separately, then compared value by value. All 68 keys agreed, including two famous era boundary cases that both authors filed identically without seeing each other’s work.

How every quiz plays

The rules are the same on every page:

• Four options per question.
• Instant right or wrong, with the correct answer shown either way.
• A full review of the run at the end.
• Best score saved in your browser — no signup, no account.

Two things are missing on purpose. Ear training is absent because it deserves real audio, and it will arrive as its own engine or not at all. Song and artist trivia is absent because charts churn; the material here holds still long enough to be worth learning. What remains is reading, counting, and knowing — the parts of musicianship a page of drawn notation can honestly examine.
