About
Clefver
A complete music classroom companion: ear training, note reading, theory, performance and composition in one app that works offline on any device, with tools for teachers to set, share and mark work.
What's inside
Aural Skills — chord tonalities and progressions, intervals, scales, cadences, scale degrees, metre, pitch, and rhythmic, melodic and full dictation, plus error detection and chord-chart dictation.
Note Recognition — name notes in treble, bass, alto and tenor clefs (with ledger-line, landmark and 60-second sprint practice), read whole bars, spell note words, and find notes on the keyboard and guitar.
Music Theory — elements of music, dynamics, key signatures, building chords, intervals and scales, completing and fixing rhythms, transposition and musical terms.
Performance — sing it back and climb the Sight-Singing Ladder with live pitch detection, tap rhythms in time, and count and play along over a drum beat.
Learning — lessons on scales, keys, intervals, chords and form; listening guides; the Composer's Toolkit; a Circle of Fifths explorer; how synthesisers work, with a playable three-oscillator synth; transposing instruments explained step by step; strum and play along; keyboard and guitar references, scales, the Instrument Bank and elements-of-music revision.
Create — the Composition Sketch Pad and Score Creator (multi-instrument scores with dynamics, articulations, ornaments, tempo and metre changes, and PDF export; switch on Extended notation for two voices on a stave, tuplets, demisemiquavers, 8va lines and pieces up to 128 bars, and view the music as pages or one continuous line), Melody Over Chords, the Chord Chart and the Drum Step Sequencer.
Your work, kept safe — save any piece as a .clefver file, have Chrome or Edge save everything into a folder on your computer automatically, or make a full backup.
Tools — tuner, metronome, drone and reference pitch.
For teachers
Build assessments from any mix of modes and share them as a link, generate printable worksheets with answer keys, run class quizzes and collect and mark results. Elective Content unlocks the senior material across the app.
Sounds
Recorded piano, plus electric keyboard, synth, guitar, brass, woodwind, strings and marimba generated in your browser. Switch timbre with the icons at the top of each screen. In the Sketch Pad, Score Creator and Melody Over Chords the piano switches to full-length recordings (downloaded the first time, then kept offline), so held and pedalled notes ring on, and softer dynamics sound darker as well as quieter. Piano samples: the Salamander Grand Piano by Alexander Holm, from Ziya Mete Demircan’s SalC5 Light soundfont (free, non-commercial).
The Score Creator's orchestral, band, keyboard, synth and percussion instruments are sampled from GeneralUser GS by S. Christian Collins (schristiancollins.com), used under its free licence (included with the app as audio/sf/LICENSE-GeneralUser-GS.txt). Each instrument is downloaded only when a score first uses it, then kept for offline use.

Scores, compositions and progress are stored only on this device — nothing is sent anywhere. Scorecards and PDFs can be exported to hand in through Google Classroom.

The melody is built only from the notes you tick, so you can scaffold from a five-note range upwards.
How to approach this
First pass — rhythm only. Ignore pitch. Tap note values to build the rhythm left to right; Undo removes the last one.
Second pass — pitches. Drag any notehead up or down to set its pitch, or tap it and use ▲ ▼. Two quavers in a beat beam themselves.
Splitting the task this way is far easier than trying to hear both at once.
At most one per dictation, and always approached musically — by step, or as part of an arpeggio.
Lets you play back what you have written and compare it with the original by ear.
Writing it down
Click a note value to arm it, then click the stave where it goes — a preview follows your pointer. Or use Add under a value for quick left-to-right entry.

for the whole quiz. A bar counts down along the top (red when less than a fifth is left); when it runs out the quiz ends and the report says so. Each section can have its own limit too (the clock beside it).
Each student's copy is shuffled independently from the same link. Most question types already generate different questions per student — this matters most for teacher-written and vetted questions, which are otherwise identical for everyone.

Teacher guide
Everything the teacher tools do, and how the pieces fit together.
Standard and Elective Content
Standard is what a junior student sees. Elective Content unlocks the senior content — augmented and extended chords, modes and compound intervals, scale construction, full dictation, pitch and interval training.
The teacher tools are always on the menu under For teachers, whatever Elective Content is set to. When screen-sharing, turn Elective Content off to show exactly the menu your junior students see.
Quiz Builder
Assemble an assessment from any combination of sections, set the parameters for each, and generate a link. Everything is encoded in the link itself — there is no account, login, or server. Students click it and begin.
Student names — optional; when on, the quiz will not start until a first and last name is entered, and the name appears on their scorecard and report.
Instructions — free text shown to students before they start.
Feedback — withhold correct/incorrect until the end (the default) so students can't read answers off a neighbour's screen.
Custom Questions — write your own questions and multiple-choice answers for anything Clefver doesn't cover.
Differentiation — tick Support and/or Extension to generate extra links alongside the standard one, each with its own Quiz ID so you can tell them apart in the results.
Classroom Quiz
A quiz you run live from the front of the room: chords play on unlimited replay with a reveal button, so you control the pace and discuss each answer as a group. Nothing is scored or submitted.
Marking and feedback links
Open a student’s results link (or Mark and advise in Class Results) to mark their work and send it back.
Written answers get a mark (out of the question’s marks) and a comment. Ready-made advice for the concept the question asks about (duration, pitch, texture and so on) adds to the comment with one tap. In Class Results you can mark every student’s answer to a question side by side.
Areas to work on: every section under 75% starts with one piece of targeted advice ticked (for intervals, cadences, rhythm, key signatures and every other quiz type); tick or untick to suit the student.
Add an overall comment, then Copy the feedback link and send it (a private comment in Classroom, or email). Preview what the student sees shows it first. Marks are kept on your device as you type.
The student’s link opens their marked work: marks, your comments beside their answers, and each area to work on with a button to practise it (and to learn it, where there is a lesson).
Questions on a video
In a video section (or the Listening Activity Generator), Add questions on the video… opens the video large with a bar underneath. Play or drag to a moment, pause, and press + Multiple choice here, + Written answer here or + HSC-style here: the question is pinned to that moment and shows as a dot on the bar. Drag a dot, type a time or press ⏱ Now to move it. Students’ video pauses at each dot and the question appears over it.
My work (students)
Every quiz a student opens from your link appears in My Progress › My work: To do, Started, Submitted (with the results link to copy again) and Marked (with your feedback). Give a quiz a due date in the Quiz Builder and it shows on the quiz and in the list, which flags work due within two days or overdue, with a dot on My Progress.
Listening Activity Generator
A quiz built on one YouTube video or recording (a link to an .mp3 or .mp4 works too). It is the Quiz Builder’s video section, ready to fill in, and the link you share works like any other quiz link.
HSC-style aural question — choose a verb (describe, explain, discuss, analyse, compare, identify and describe), one or more concepts and, if you like, a focus such as contrast, tension or musical interest, and the marks. Clefver words the question (“Explain how duration and texture are used to create contrast in this excerpt.”), adds a planning grid for those concepts and writes marking guidelines in bands. Everything stays editable.
Elements of music prompts — the listening log’s concepts (and the compositional principles), each a toggle that adds or removes a written box with its guiding questions.
Any question can be multiple choice (marked automatically) or a written answer (you mark it). Give it marks, a size, a hint, a planning grid and guidelines; times in the video still open and pause each question.
Students see the marking guidelines and say which band they think their answer reaches. Their writing is saved on the device as they go, so a reload loses nothing.
Written answers arrive in the results link, with the self-assessment and planning notes, and in the PDF. Class Results puts every student’s answer to each written question together, ready to mark side by side. The score counts only the multiple-choice questions.
Puzzle & Activity Generator
Makes a crossword, a find-a-word, or both, as a printable A4 PDF with the answers on the last page (leave that page out when you print). Good for a relief lesson.
Terms from Clefver — the Elements of Music glossary (by concept), the Italian terms and signs from Learn Signs and Terms, notation and instruments. The definitions become the clues. Elective terms come in only when ticked.
Your own terms — one per line as term - clue. They are always used; random picks from the ticked lists fill up to the number of words you choose.
New words picks again; New layout keeps the words and rearranges the grid. Multi-word answers are written without spaces, with the letter counts in brackets, e.g. (5,4).
Find-a-word directions go from across-and-down (easiest) to any direction, including backwards. List the clues, not the words makes students work out each term before finding it.
Unscramble — jumbled letters, missing letters, or a mix, each with its clue; the first letter can be given for an easier version.
Match-up — terms and definitions as a worksheet (draw lines or write the letter), or as cut-out cards for a card sort.
Term bingo — terms on the cards; the caller reads out the definitions (from the caller sheet, or project them with the on-screen caller and reveal the answer).
Listening log — the six concepts with guiding questions and glossary prompt words, one piece a page or up to three side by side. It suits any recording, so it is ideal to leave with a playlist.
Note-name code breaker — words (or your own secret message) written as notes in treble, bass or both, on the stave or with ledger lines; students write each letter in the box beneath its note. Letters that are not note names are printed for them.
Rhythm maths — sums of note and rest values in crotchet beats, at three levels: answers in beats, as one note, or a mix that includes finding the missing value. An optional key of note values at the top supports younger students.
Instrument fact file — a research page: draw and label, family, classification, clef, range, timbre, techniques, where you hear it. Tick instruments for a page each and a teacher page of key facts, or none for a student's-choice page.
Rhythm bingo — pick the note values, one bar of 4/4 or two beats a square, 3 × 3 (with a free centre if you like) or 4 × 4, and how many cards. Every card is different, four to an A4 page with dashed cut lines; the last page is a numbered caller sheet. The Caller on screen counts in and claps each rhythm, so whoever runs the game does not need to read rhythm.
Class Results
Students finish an assessment and get a results link to submit. Paste any number of those links into Class Results and you get one merged view: the class average, median and range; every section ordered weakest first; the individual questions the class found hardest; and a per-student list ordered lowest first, tagged where someone sat a differentiated version or was on a repeat attempt.
All of it runs on this device — nothing is uploaded anywhere.
Reading a student's report
Each results link opens a full report: every question, what the student answered, whether it was right, and the exact settings that section used. Repeat attempts are marked, as is the differentiated version if they sat one — along with the specific adjustments it made.
Practical notes
Have students open the app once before the lesson so the piano samples cache; thirty devices downloading at once on school wifi is slow.
The assessment intro screen has a sound-check button — worth insisting on it before everyone starts.
If a banner offers a refresh, take it: it means a newer version is available.
Links never expire and contain no personal data, so they are safe to post in Google Classroom.

How to type a chart
| is a barline and || a double barline. |: and :| are repeat signs (played twice).
Chords in a bar share it evenly: |Em7 G | in 4/4 is two beats each.
For exact beats, use / for each beat the chord carries on: |C / / G | is three beats of C and one of G.
Type a time signature to change metre from that bar: |3/4 Em G F | G Am F | 4/4 G / C / ||. The quaver stays the same speed through a change.
Time endings: type 1st, 2nd or 3rd at the start of a bar. |: C | G | 1st F | G :| 2nd F | C || plays the 1st ending the first time and skips to the 2nd the next.
Click any chord in the chart to hear it on its own.
% repeats the previous bar, N.C. is no chord, [A] puts a section letter on the bar.
Start a new line to start a new row. Rows also wrap every four bars.
Key sets the key the chart is in. Choose a different key and every chord is transposed to it, spelt for the new key.

Privacy and accessibility
Clefver is a music-education app that runs entirely in the browser. It has no accounts, no sign-in, no advertising, no analytics or tracking, and no cookies. Everything a student does stays on their own device unless they choose to share it.
What Clefver keeps, and where
Settings, practice history and results, compositions and their autosaves, composition folios (diary entries and versions), each piece’s time-lapse (the saved moments of how it was written), lesson progress and recently used tools.
All of it is kept in the browser’s own storage on this device only. It is never sent to Clefver or anyone else.
Names are optional. A student may type their name on a scorecard, a quiz or a folio. It stays on the device, and goes only where the student sends it.
Clearing the browser’s site data erases it. Students can keep their own copy as a backup file or a .clefver file (Settings › Your Data), or in a save folder they choose on their device.
What leaves the device
Nothing leaves automatically. Only these, and only when the user chooses:
Links they create and share: a quiz, results, feedback or composition link carries its content inside the link itself. A results link, for example, includes the student’s name (if typed) and their answers, and anyone the link is sent to can read them. There is no copy on a server.
Files they save or export: PDFs, pictures, MusicXML, MIDI, audio and Clefver files go wherever the user saves them.
Share to Google Classroom opens Google’s own sharing page with the link; Google’s terms apply there.
YouTube videos in listening activities and video questions (only when a teacher has used one) play through YouTube’s privacy-enhanced player (youtube-nocookie.com); YouTube’s terms apply to the video.
The app’s own files and instrument sounds download from the website that hosts Clefver. Like every website’s host, it may keep standard technical request logs; Clefver itself does not collect or use them.
Microphone and MIDI
The microphone is used only when the user starts a tool that listens: the tuner, singing exercises, and singing or playing a melody into the Score Creator. The browser asks permission first.
Sound from the microphone is analysed live, on the device, to find its pitch. It is never recorded, stored or sent anywhere.
A MIDI keyboard, if connected, is read on the device in the same way.
For schools
Students need no email address, account or personal details to use any part of Clefver.
Teacher tools (quizzes, results, support packs, feedback) work the same way: everything is created on the teacher’s device and shared only as links or files the teacher chooses to send.
Clefver can be installed as an app and works offline once its sounds have downloaded.
Accessibility
Display: Dark Mode, Larger text, Dyslexia-friendly text (more letter, word and line spacing), Reduce motion (it also follows the device’s own setting) and a Stronger focus outline, all in Settings.
Keyboard: the menus, quizzes and tools can be used with Tab and Enter; quizzes take number keys for answers and Enter to check; notes can be entered in the Score Creator from the computer keyboard or a MIDI keyboard.
Screen readers: buttons and controls are labelled, and many status messages (saving, results, feedback) are announced.
Colour is never the only signal: colour-coded things (elective tools, chord types, motif types, right and wrong answers) also carry a word, a symbol or a label.
Projector mode shows lessons and maps in large type for the whole class.
Known limits. Music notation is drawn as a picture, so a screen reader can describe the controls but not read a score note by note. Aural training depends on hearing; where possible the answer is also shown on a stave or keyboard afterwards.

What is an upper structure?
An upper structure is a triad played on top of a chord, usually by the right hand, while the left hand plays the chord’s 3rd and 7th (often with the root). The left hand tells you what kind of chord it is; the triad on top adds the colour notes — the 9ths, 11ths and 13ths, natural or altered.
Because a triad is easy to find and play, it is the quickest way to reach a rich jazz sound: think “D major over C7” instead of “C7 with a 9th, a sharp 11th and a 13th”. Each triad comes from a scale that fits the chord, so it always belongs.
The left hand keeps the 3rd and 7th: they decide major, minor or dominant. The 5th and the root can be left out (a bass player has the root).
The right hand plays a triad from the chord’s scale. Its top note is the one people hear as the melody, so choose the inversion for the top note you want.
Avoid a natural 11 over a major 3rd (it clashes a minor 9th above it) — that is why the major-chord structures use ♯11.
Writing it down: an upper structure is written as a polychord, the triad above the chord with a horizontal line (D over C7). A diagonal slash (D/C) is different: a D triad with just C in the bass. Lead sheets usually show the full symbol instead, such as C13(♯11).

All the transposing instruments
What is a synthesiser?
A synthesiser makes its sound rather than recording one. It starts with an electrical signal that wobbles back and forth hundreds of times a second — the oscillator. Your speaker moves with that wobble, and you hear it as a note: the faster it repeats, the higher the pitch.
The raw signal then passes through a filter, which shapes its tone, and an amplifier whose envelope decides how the note starts, holds and dies away.
Oscillatorpitch and waveform→Filtertone: bright or dark→Amplifierenvelope: ADSR→Speakerwhat you hear
Oscillators and waveforms
The shape of the wobble is the waveform, and it decides the timbre. Every shape except the sine is secretly a mixture of a note and its harmonics (quieter notes at 2×, 3×, 4×… the pitch). The more harmonics, the brighter and buzzier the sound. Press each one to hear it.
Pitch, octaves and detune
Doubling the speed of an oscillator raises it an octave; halving it drops it an octave. Big synth sounds often stack two or three oscillators an octave apart.
Detune nudges one oscillator a few cents (hundredths of a semitone) away from another. The two drift in and out of step, making a slow beating that sounds wide and lively — the classic “supersaw”.
The envelope: ADSR
An envelope changes the volume over the life of a note, in four stages:
Attack — how long it takes to reach full volume after you press the key (a pluck is instant; a string pad fades in).
Decay — how long it takes to fall from that peak to the sustain level.
Sustain — the level it holds at while the key stays down (not a time).
Release — how long it takes to fade out after you let go.
The filter: tone
A low-pass filter lets the low part of the sound through and cuts the high harmonics above its cutoff. Turn the cutoff down and a bright sawtooth turns warm and muffled; turn it up and it opens out. Resonance boosts the harmonics right at the cutoff, for a vocal, “wah” edge.
FM synthesis
An FM (frequency modulation) synth makes its sound differently. A second, unheard sine wave, the modulator, wobbles the pitch of the one you hear, the carrier. Slowly, that would be vibrato; this fast, the wobble turns into new overtones called sidebands. This is the sound of the 1980s: the electric pianos, bells and basses of the Yamaha DX7.
Ratio: the modulator's speed against the note. Whole numbers (×1, ×2, ×3) put the sidebands on the note's own harmonics, so it sounds pitched; in-between ratios (×1.41, ×3.5) scatter them, so it sounds like a bell or metal.
Index: how hard the modulator pushes. At 0 you hear a pure sine; turn it up and more sidebands appear, so the sound gets brighter.
Brightness envelope: the index rising and falling during the note. A bright attack that mellows is what makes FM sound like an electric piano or a struck bell.
Ready? The You Try tab has a playable three-oscillator synth with all of these controls. Choose FM on any oscillator, or one of the FM presets.
Tap an oscillator to change its waveform, octave, envelope and tone. Play with the keys below, or your computer keyboard: A S D F G H J K L ; ' are the white notes, W E T Y U O P the black ones; hold Tab for an octave higher, Z/X move the whole keyboard down/up.

How the DAW works
Idea Stems… is a library of ready-made loops — drum grooves and ostinati, chord progressions, melodies and bass lines — that come out in the project’s key and metre: hear one, then Add it at the playhead, or ✦ Mutate it to make it more complex (extensions and inversions, passing notes, fills and ghost notes…), choosing which changes to keep. Or double-click (or double-tap) an empty part of a track to add a clip, then double-click the clip to write its notes in the piano roll. Drag a clip to move it — to another time or another track. At its right edge, the top half makes the clip longer or shorter (hold Alt/Option to stretch the notes with it) and the bottom half ⟳ loops it, repeating its notes as far as you drag. Up to eight tracks, each with its own instrument — tap a track’s icon to choose another. Under the tracks, the selected track’s volume and effects sit beside the Master: the volume of the whole mix, its level meter (keep it out of the red; the light shows if it clipped) and up to three effects on everything. [ and ] move the playhead back and forward a bar. ✂ Split at playhead (S) cuts a clip in two where the playhead is, and Join with next (J) makes the selected clip and the next one on its track into one (both are on the right-click menu too). ● Record (R) counts in a bar, then records what you play into the selected track — on a MIDI keyboard, the on-screen Keyboard or your computer keys; with the loop on, each time round adds to the same clip. The Tone, Space, Echo and Drive knobs shape a track without opening any effects. Drum clips open on a step grid: click the squares to make a beat (Shift-click for a louder, accented hit). Open in Score Editor writes the selected clip in standard notation and brings your changes back.
Piano roll
How the step grid works
Each row is a drum and each square a semiquaver (four to a beat). Click a square to add a hit and click it again to take it away; drag along a row to fill or clear several. Shift-click makes a hit louder (an accent, shown darker). Click a drum’s name to hear it. The arrow keys move round the grid and Space switches a square on or off. Piano roll shows the same notes with their exact timing.
How the piano roll works
Click the grid to add a note (drag to make it longer). Drag a note to move it, drag its right edge to change its length, and double-click it (or press Delete) to remove it. Turn Note entry off (N) — or hold Shift — to drag a box round notes and select them; selected notes move, change velocity and delete together (Ctrl/⌘+A selects them all). Click a key on the left to hear it. Choose a Key and scale (major, minor, pentatonic, blues, the modes…) and only the notes in it are shown, so every note you write fits; the up and down arrows then step through the key, and Fit notes to the key moves any stray notes in. Quantise (Q) lines the notes up with the grid and Humanise loosens them a little.
Chords
How to type the chords
Type chords as in the Chord Chart: | between bars, and one chord in a bar fills it (two share it, and so on). A / is one more beat of the chord before it, so Am / / Em puts Em on beat 4. Without any |, each chord or / is one beat. Slash chords set the bass note for an inversion: C/E, G/B. The notes go into the clip; open it in the piano roll to change them.
Effects
What is an effect?
An effect changes a sound on its way to the speakers. The untouched sound is called dry; the processed sound is wet, and a mix control blends the two. Effects are chained one after another — a guitarist’s pedalboard, or the inserts on a DAW track — and the order matters: distortion before reverb sounds very different from reverb before distortion.

Telling Tonalities Apart
Major — ConsonantHappy, bright, warm. Feels settled and resolved.
Minor — ConsonantSad, mellow, reflective — but still feels stable, like it could end there.
Diminished — DissonantTense and crunchy — the notes sound close together. Wants to resolve upward, like the second-last chord in a progression.
Augmented — DissonantAnxious, spread-out notes. Where it resolves next feels ambiguous and suspenseful.
Strategy: first decide consonant (stable — major/minor) or dissonant (unstable — diminished/augmented) to eliminate options. Stuck between minor and diminished? Imagine the song ending right there: minor would sound finished, diminished would sound like the music still has somewhere to go.
