Tuner
Chromatic — any instrumentUkulele
Four strings — G C E AIn Tune?
The four strings play one by one. Your call: is the whole uke in tune, or is something off? Strum them together and hear the wobble two almost-tuned strings make.
PlayOut of Tune?
One string is out. Listen, then pick the string that's off. Trains you to pin down exactly where the sour note is coming from.
PlayChord Quiz
A chord name pops up — tap the frets to build the shape from memory, then check your work. Graded on the shape, not the fingering.
PlayUke Progress
A run of ukulele chords plays, played with the same shapes you're learning — the last card is blank, so name the chord you hear. Starts with C, G, Am and F and adds one more each level up to the sevenths and Gm.
PlayWhat Note?
A marker lands on an open string or the first three frets — work out which note that is, then tap its name on the little piano keyboard. Naturals to start, full chromatic when you're ready.
PlayGuitar
Six strings — E A D G B EIn Tune?
Six strings, played in turn. Decide whether the guitar is in tune or out. Strum them together to hear how an off string clashes.
PlayOut of Tune?
One of the six is out. Find it by ear and pick the string that's off — the ear-test you'd use tuning a guitar for real.
PlayChord Quiz
A chord name pops up — build the shape by tapping frets and muting strings, then check it. Easy, medium and hard chord sets.
PlayGuitar Progress
A run of guitar chords plays, played with their real shapes — the last card is blank, so name the chord you hear. Ramps from the simple open chords through 7ths and maj7s up to movable barre shapes.
PlayWhat Note?
A marker lands on an open string or the first three frets — work out which note that is, then tap its name on the little piano keyboard. Naturals to start, full chromatic when you're ready.
PlayTriad Drop
You're handed a triad grip and a chord name — slide it up or down the neck to the one fret where the shape spells that chord. Majors, minors and all three inversions.
PlayTriad Launch
Same puzzle, launched. Charge a power meter and fire the grip up the neck — it slides, bounces and settles. Land it on the fret that spells the chord: 3 points spot-on, 1 within a fret.
PlayPiano
One octave — build the chordChord Catapult
Fling a note in an arc onto the keyboard and strike the keys that spell the chord — C, E, G. Fifteen levels climb from triads through inversions, 7ths, 9ths and diminished chords, with trees, clouds and crosswind in the way. By the time you beat the wind, spelling chords is automatic.
PlayChord Cascade
A chord's key-shape drops from the sky — scroll the piano roll so it lands on the keys that actually spell it. Since every chord's black-and-white pattern is unique, it only clicks in one place. Ramps through minors, inversions, 7ths and 9ths — chord spellings stick before you notice you've learned them.
PlayEar Training
By ear — arcade stylePitch Invaders
Aliens fall down the lane of their note — tap the matching note to shoot them down. Climb the levels and they cloak, so you go by ear alone. Boss waves play a run of notes to echo back.
PlayPitch Invaders — Chromatic
The full twelve notes on a piano keyboard, sharps and flats included. Start on the white keys, then a new accidental joins every few levels so your ear can settle before the next. Cloaked aliens push you to go by ear.
PlayPitch Invaders — Circle of Fifths
Only the seven notes of the key fall as aliens, and those piano keys glow to guide you. Clear a boss wave and the wheel spins to a new key — a quick home-note cue re-anchors your ear before the aliens return.
PlayChord Progress
A chord progression plays with a marker sweeping across it — the last card stays blank. Name the chord you heard from the key's chords. Later levels add more chords, longer progressions, and inversions to spot.
PlayTheory
Read it — play itRhythm Runner
Read the bar of rhythm, then the road opens into holes shaped like the notes. Hold to stay airborne for long notes, land on the rests — don't fall in or hit the ceiling. Beamed quavers, dotted notes and syncopation as the tempo climbs — keep running and you're reading rhythm at sight, no counting on fingers.
PlayBar Packer
Pack a suitcase-shaped bar with the right note blocks so it fills exactly — no gaps, no overflow. A limited hand with a spare or two makes you work out which notes add up. Fill it and hear the rhythm play back. Meters vary from 4/4 to 6/8 and 7/8.
PlayThe Missing Piece
A bar drawn as a jigsaw with one piece missing. Pick the note-value piece that fills the hole exactly — the surgical "what plus an eighth makes a beat?" drill. It snaps in and plays back. Meters and note values widen as you climb.
PlayFix the Plank
A bar of note-planks with one cracked. Pull the broken plank out, then rebuild its length from smaller planks — the exact note isn't in your pile, so a half note becomes two crotchets. Fill the gap and the bar plays whole again.
PlayNote Reading
A note appears on the stave — name it before the clock runs down. Trains your reading across the lines and spaces, from the easy middle notes out to the ledger lines.
PlayScale Climb
Tap the scale's next note on the piano keyboard to climb a step — and stay ahead of the barrels rolling down. Which note comes next in the scale, under pressure.
PlayApple Shot
Read the apple's note on the stave, hold to draw the bow, and let go just as your aim crosses that note — William Tell for note reading.
PlayHidden Words
Each note on the stave stands for a letter — read them in turn and type to spell the hidden word (BEEF, CAGE, FACE and friends).
PlayNote Elevator
Read the note, then press its floor to send the lift there. Quick-fire stave reading up and down the building, faster as you go.
