The Teacher's Handbook

How to use Interval Hero with your piano students, from the first lesson onwards.

  • Connect your students

    One join code brings them onto your roster.

  • Build a practice habit

    Game Mode guides them. The mic checks playing.

  • See what needs attention

    Review activity and first-try scores together.

Start with your first student

Set things up together in a lesson, so home practice feels familiar.

  1. Get teacher access

    Request a signup code, register as a Teacher, and wait for approval.

  2. Log in and take the guide

    You land on My Students, your dashboard. A screenshot guide walks you through it the first time; reopen it any time with 📖 How to use Interval Hero.

  3. Walk the path yourself

    Complete all 7 Game Mode levels on your own account first — every level is unlocked for teachers — so you know what each step asks before a student hits it.

  4. Share your join code

    Your six-character code sits on the dashboard. Give it to the student’s parent or responsible adult.

  5. Create their account

    On the sign-up page, choose Student and enter the join code. One account per student.

  6. Choose Free or Pro

    Start free, or grant a Pro seat — Teacher Pro includes 3 seats, more available anytime.

  7. Test the mic together

    For Play the Note, allow microphone access and try a few notes near the piano before practising at home.

One path. Seven small steps forward.

Tell your student: “Open Game Mode and keep going.” Its 30 sub-levels introduce one small addition at a time. Passing each one opens the next.

  1. Level 1 · Free

    5-Note Range

    Read within a five-note span.

  2. Level 2 · Free

    Chain

    Follow wider intervals from note to note.

  3. Level 3 · Free

    Guide Notes

    Find your grand-staff landmarks.

  4. Level 4 · Pro

    Find the Start

    From the nearest guide note, count to the note.

  5. Level 5 · Pro

    Challenge

    Read the five-note range against a timer.

  6. Level 6 · Pro

    Play the Note

    Read it, then play it on your piano.

  7. Level 7 · Pro

    Chord Inversions

    Recognise a whole chord shape.

Free gets them started

Levels 1–3 are free, with a 40-question daily allowance outside Game Mode (Game Mode itself is exempt).

Pro takes the path further

Pro removes the daily cap and unlocks Levels 4–7 as progression allows. Teacher accounts have all seven levels open regardless of plan.

Game Mode or mode tabs: which should I use?

Game Mode introduces material in order. Mode tabs let students practise freely once they've passed the corresponding level. Pro grants access; it doesn't skip the sequence. For a specific focus before a mode unlocks, send an assignment instead.

Pick the skill you want to build

Game Mode for the overall journey; a focused session when you know what needs work.

5-Note Range

Free

Read intervals within a five-note span.

Builds: confidence in a small, manageable range.

Teaching tip

Start here with a new reader. If they guess, check whether they can identify the starting note before adding wider intervals.

Chain

Free

Each new interval starts where the last one ended, up to an octave away.

Builds: reading relative to the previous note.

Teaching tip

Ask students to describe direction and distance from the last note. Keep the range small until they stop counting from Middle C each time.

Guide Notes

Free

Name a landmark on the staff, or find a named landmark.

Builds: reliable anchors in both clefs.

Landmarks and teaching tip

Six positions: Middle C in each clef, Bass C, Treble C, Low C and High C. Name the Note asks for a name; Find the Note asks for its position. For a bass-shy student, assign the bass-side landmarks first.

Find the Start

Pro

One note on the grand staff. The student puts a C near it on its exact line or space (tap, slide or the arrow buttons, then Check), then chooses the interval and direction from that C. A note that lands on any other line or space is wrong and named (“That’s a D, not a C”), so tapping roughly near the C no longer passes. In Level 4.3 the C is never drawn: the blue note starts a bar of four, the student picks the C by name and counts from it in their head, as on real sheet music.

Builds: finding the first note of a piece from a landmark, the step between Guide Notes and Play the Note.

How it works and teaching tip

Any C on the note's staff that is no more than a 5th away counts: D and E count up from the C below, A and B down from the C above, and F and G work from either (F5 is Treble C and a 4th up, or High C and a 5th down). Step 2's answer follows whichever C the student picked. Both steps must be right first time to score. Counting arrows show the path after each answer.

Play the Note

Pro

Read the note and answer on the piano. The mic checks the pitch; MIDI also works.

Builds: the connection between reading and playing.

Variants and teaching tip

Practise Chain, 5-Note Range, Guide Notes or Chord Inversions with played answers. Start with familiar material — finding the right key is a new task on its own.

Each session asks Mic or MIDI first, then gives 15 seconds to play the first note, counting down in red for the last 5. Late still lets them play on; it just doesn’t count as a first try.

Challenge

Free + Pro

Answer as many questions as you can before the timer ends.

Builds: speed on material already understood.

Access and teaching tip

Free sub-modes follow their usual unlocks; Play the Note, Chord Inversions and the Level 5 Test Run need Pro. A short timer suits an accurate but slow reader — if speed brings guessing, return to untimed practice.

Chord Inversions

Pro

Recognise root position and inversions in block or broken chords.

Builds: reading groups of notes as shapes.

Chord types and teaching tip

Triads cover root, 1st and 2nd inversions; 7th chords add a 3rd. Try Broken Chord first for a one-note-at-a-time reader, then Block Chord once they see the whole shape.

Make the dashboard a weekly habit

Everything below lives under My Students. Assign one focus, check what happened, decide what's next.

  1. 1. Assign

    Pick a student or your roster. Choose a mode and a specific focus.

  2. 2. Practise

    The student opens Assignments and starts the prepared activity.

  3. 3. Review

    Check activity, completion and scores before the next lesson.

  4. 4. Adjust

    Repeat a weak area or move on when the student is ready.

Read these signals together

Activity

Free / Pro

Set an assignment that is easy to follow

Give it a clear label ("Bass clef landmarks"), pick the mode, and narrow the content — add a pass mark, question count or due date if useful. For Find the Start, tick which guide notes to count from. The student's Start button loads it; a qualifying session marks it done and shows the score on your dashboard. Students who’ve turned on notifications get a push the moment you assign it.

An assignment can open a Pro mode for a free student for that activity only — it doesn't grant permanent Pro or lift their daily allowance elsewhere.

Manage Pro seats and subscriptions

Grant or remove teacher-funded Pro from the dashboard, within your seat allowance; add seats as needed. A student's own subscription is separate and not yours to downgrade.

If you cancel Teacher Pro, access continues until the paid period ends, then granted seats return to Free and the dashboard goes read-only. Students keep their progress and any subscription they bought themselves.

Reset a password or remove a student

Use Reset password on your roster — no student email needed. With an email on file, they can also use Forgot your password? themselves.

Removing a leaving student drops your assignments and teacher-granted Pro, but keeps their account, progress and any subscription they bought themselves.

Use the roster on a phone or tablet

On a phone, a tablet, or any screen under 900px wide, each student is a compact card: name, Free/Pro, last activity and assignments. Tap a card to open the rest, with every field labelled and the actions underneath.

Choose your inactivity and leaderboard settings

Set the inactivity threshold to match your agreed practice routine. The studio leaderboard is on by default; switch it off if competition doesn't suit your students.

A green note and a score tell different stories

Only the first answer scores. A note can turn green after a retry, but that correction does not increase first-try accuracy.

Illustrative example · Five questions, one corrected after a retry
  1. 1First try
  2. 2First try
  3. 3After retry
  4. 4First try
  5. 5First try
4 out of 5 = 80% first-try accuracy

The first answer was correct on four questions.

All 5 eventually correct

The student corrected question 3. That is useful learning, even though the score stays 80%.

Checkpoints bring the skills together

A mixed assessment of Guide Notes, Find the Start, Chord Inversions and Play the Note, unlocked by progress rather than a calendar and carrying no penalty. Use the result to choose the next teaching focus.

My Progress, challenges and the leaderboard

Four things your students will ask about, all under the three-line menu button. Weekly Challenge, Ranked Practice and the Leaderboard need Pro; My Progress is on every account.

Where they are

Open the menu and the four items sit together, right under Game Mode.

  1. Open the menu

    Tap the three-line button at the top right, then any of the four ringed items. A locked item shows a padlock: that account needs Pro.

    The app menu with My Progress, Weekly Challenge, Ranked Practice and Leaderboard circled in red.

My Progress

A record of every finished session, updated the moment it ends. Reading Level and the skills breakdown are Pro; the rest is on every account — but it only ever shows your own practice. For a student's, open it together on their device, or read My Students: Last Activity, Checkpoint result and assignment scores.

  1. The summary

    Six figures: Reading Level out of 10, first-try accuracy, total questions, sessions, day streak and average response time, plus one line of advice on what's next.

    The top of My Progress: six stat cards, a strong-across-the-board message, the reading skills groups and the first trend chart.
  2. Your reading skills

    Three groups — Intervals, Guide Notes, Chord Inversions. Tap one for a bar per interval size, landmark or inversion (needs 5+ first-try answers to count).

    The Intervals group expanded, showing a green accuracy bar for 2nds through Octaves.
  3. Progress over time

    One chart per mode, one bar per practice day, switching between Accuracy, Response time and, once unlocked, ⚡ App score. Tap a bar for the exact figure and date; below is a worst-first table and a day-by-day log.

    The Progress over time charts with a tapped bar showing 85%, 11/09/2026, 17 of 20 first try.

Weekly Challenge

One fixed, server-graded question set each week, identical for everyone, one attempt Monday to Sunday. The format rotates through four: Sprint (2 minutes, most correct wins), Speed 30 (30 questions, fastest time: a wrong answer adds 5 seconds and, from 12/10/2026, a right one takes 1 second off, shown beside the clock), Sudden Death (first mistake or 10 minutes ends it) and The Full Sweep (40 questions across everything taught).

  1. Read the rules, then Start

    The first open each week shows this card. Nothing starts until you tap Start — that's your one run for the week.

    The Sudden Death rules card: how it works, good to know, and a Start button.
  2. Play it

    Looks like normal practice, clock/streak/count along the top. Only the first tap counts — no retries here.

    A Sudden Death run in progress: 9:59 on the clock, streak 0, question 1, an interval on the staff and answer buttons below.
  3. Your result

    Ask students to play early in the week, not Sunday night. A low Sudden Death streak usually points at one interval size — My Progress shows which.

    The Weekly Challenge card after playing: already played this week, 27 questions in a row.

Ranked Practice

Ordinary practice that counts: 1 point per correct answer toward the week's leaderboard, plus a bonus for 75%+ or 90%+ sessions. Capped at 60/day, so steady daily practice beats one big cram — the behaviour you want anyway.

  1. Pick a mode

    Chain, Guide Notes, Find the Start or Chord Inversions, 20 questions each.

    The Ranked Practice picker with four modes: Chain, Guide Notes, Find the Start and Chord Inversions.
  2. Answer 20 questions

    Same screen as the Weekly Challenge. Points bank only when question 20 is answered. Closed early? Pick the same mode again the same day to carry on where you stopped, or tap Resume on Home.

    A Ranked Practice Chain session: question 1 of 20, correct 0, an interval on the staff and answer buttons.

Leaderboard

Exactly what your students see, minus the name box: your roster ranked by points or challenge result on the Ranked side, and by App score points on the ⚡ App score side. You're never listed. Needs 4+ scoring players to show a ranking.

App score

A reward for students who have finished the path. It unlocks once a Pro student has passed all seven Game Mode levels, practised 5 hours or answered 2,500 questions, and reached a Reading Level of 8.5. Until then, students see a countdown on Home with a preview of what theyand reached a Reading Level of 8.5. They choose whether to switch it on.

rsquo;ll unlock. Once there, they choose whether to switch it on.

  1. Points for speed

    A clock runs on every practice question, in the top-left of the staff. A right first answer scores by speed (see the table below, where most modes means 5-Note Range, Chain, Guide Notes and Chord Inversions); a wrong first try or Show Answer scores 0. Checkpoint, the Challenge tab and mistake reviews never score.

  2. What students see

    Their points beside the timer, a session total, this week against last week on Home, an App score tab in My Progress, and their best session per mode, kept each week.

Your students’ Home screen

Students land on Home after signing in. Worth a look together in the first lesson.

  1. Jump to and today’s goal

    Big buttons for Practice, Game Mode, My Progress and Assignments, and a ring that fills toward a daily goal of 10, 20, 30 or 40 questions.

  2. Streaks and quests

    Badges at 3, 7, 14, 30, 50, 100, 200 and 365 days in a row, and a Daily Quest: the next Game Mode level, then two tasks from their weakest areas.

  3. Reminders

    Students who tap Enable notifications on their account page get a reminder at 6pm their time on days they haven’t practised, to keep their streak going, and a push the moment you assign something. On iPhone or iPad they add Interval Hero to the Home Screen first.

Checkpoints and ranks

Two ways the app sums up progress over the long run: a Checkpoint measures it on a given day, a rank tracks it continuously.

Checkpoints

A short mixed assessment the app schedules automatically: 50 questions in 18 minutes, one attempt, drawn from the three skills that matter most for reading at the piano. Pro-only, not pass-or-fail, and the score comes straight to your roster — think of it as a term test the app sets for you.

When one comes up. The first unlocks once a sub-level is passed in each of Guide Notes, Play the Note and Chord Inversions. After that, every 5 further sub-levels — or every 5 sessions once Game Mode is finished. Questions are always set at the hardest sub-level passed, so it's always on material actually learned.

  1. The announcement

    Appears on Home when a Checkpoint becomes available. Let me practice more puts it off with no penalty.

Settings

One panel to shape a session to the student in front of you — clef, interval width, direction, length — showing only what the open mode needs. Changes wait for Apply, and nothing here is saved between visits; for a focus you want to stick, send an assignment instead.

Opening it

Tap Settings in the header, between the menu button and the theme toggle. Tap again, or anywhere outside, to close it — or press S on a keyboard.

  1. The Settings button

    Always in the header, in every mode. It lights up while the panel is open.

What the panel shows in each mode

The top changes per mode; Playback, Difficulty and Display at the bottom stay the same everywhere.

  1. 5-Note Range

    Clef: treble or bass. Starting Note: Random or a fixed landmark. Session Length: 10, 20, 50 or Unlimited.

    The Settings panel in 5-Note Range mode: Clef, Starting Note with Random selected, Session Length 20 notes, then Playback.

  3. Chord Inversions

    Chord Type switches triads to 7th chords (adds a 3rd inversion). Guide Notes has no controls of its own beyond Session Length.

  4. The shared controls

    Playback: untick Play sound to silence auto-play and the ▶ button — clicking a note on the staff still plays it, since that's a deliberate check, not the app giving away the answer. Difficulty: Adaptive asks more of the sizes a student gets wrong most. Display: untick Show notes on staff to answer from sound alone (needs Play sound on) — a reading drill becomes ear training.

    The lower part of the Settings panel: Playback with Play sound and Auto-play new question ticked and speed Fast, Adaptive difficulty ticked, Show notes on staff ticked, and the Cancel and Apply buttons underneath.

Apply and Cancel

A changed control doesn't take effect until Apply, which only lights up once something's changed.

Get unstuck

Start with the simple checks. Test microphone problems together in a lesson.

Where is the Teacher Dashboard?

It's My Students — you land there automatically on login. Or bookmark game.interval-hero.app/teacher-dashboard.html.

How do I give a student Pro?

My Students → Roster → tap Upgrade next to their Free badge; Downgrade takes the seat back. Teacher Pro includes 3 seats, more via Change seats. A student's own subscription doesn't use one of yours.

The microphone is not picking anything up
  1. Allow microphone access in the browser's site settings.
  2. Check the selected input if the device has more than one microphone.
  3. Close video calls or other apps using the microphone.
  4. Move the device closer to the piano and test a clearly played note.

For quiet or high notes, try a firmer touch. MIDI works too, for compatible keyboards.

The student played the right note, but it was rejected

Release the pedal and let the previous sound fade; check the octave as well as the note name. For Chord Inversions, roll the chord bottom-up so the app hears each note.

A student forgot their password

With Teacher Pro active, reset it from your roster. With an email on their account, they can also use Forgot your password? themselves.

Can two students share an account?

No — give each their own; a shared account mixes progress, ranks and assignments. Free accounts are available.

Does every student need Pro?

No. Start free with Levels 1–3; grant a seat when they're ready for Level 4 or need ongoing Play the Note/Chord Inversions. See Free and Pro above.

What happens when I cancel Teacher Pro?

Access continues until the paid period ends, then granted seats return to Free and your dashboard goes read-only. Students keep their progress and any subscription they bought themselves.

Chrome says an application is stopping it from safely connecting

If the message mentions Fortinet, a school or office firewall is inspecting web traffic and Chrome refuses to trust it. This is not the app, and every secure site on that network is affected.
