How to play

Add up note values in beats and tap the answer, or build notes worth the same as the one shown by clicking note symbols. Four bars are shown, each missing some notes.
Drag notes onto a bar (or tap a note, then the bar) so every bar adds up. Tap a note you added to take it out, then press Check. Two bars are shown with the time signature missing.
Count the beats in each bar and drag the time signature that fits onto the "?". Two bars of separate quavers and semiquavers are shown.
Drag across notes to beam them; tap a beam to break it. Press Check when you are happy. Four bars of notes are shown with no bar lines.
Tap between the notes where each bar ends.

Note Ninja — Cheat Sheet

Note values (beats in 2/4, 3/4 and 4/4)

Dotted notes: a dot after any note makes it longer by half of its value (dotted minim = 2 + 1 = 3 beats; dotted crotchet = 1 + ½ = 1½ beats; dotted quaver = ½ + ¼ = ¾ beat).

Time signatures

The top number says how many beats are in a bar; the bottom number says what kind of note is one beat (4 = crotchet). The first beat of every bar is the strongest.

6/8 is different: it has two beats in a bar, and each beat is a dotted crotchet (three quavers). Notes are grouped into those two dotted-crotchet beats, counted 1 & a, 2 & a. So six quavers are written 3 + 3, never 2 + 2 + 2 (that would look like 3/4).

Beaming

Beam quavers and semiquavers so each beat is its own group: you can see where every beat starts.
In 4/4, never beam across the middle of the bar (between beats 2 and 3); four quavers in beats 1–2 or 3–4 may share a beam.
In 6/8, beam in dotted-crotchet beats: groups of three quavers (or six semiquavers).

White keys ascend in order C D E F G A B, then repeat. The two-black-key group sits between C–D–E; the three-black-key group sits between F–G–A–B. Find C: it's the white key just left of the two black keys.
