ClefQuest

You don’t train your ear by reading definitions — you train it by predicting a sound and then hearing it. Here you play an interval or chord, say what it is, and a real Web-Audio engine plays it back while the theory model checks you — the interval and chord are generated from the rules, so the answer is exact, and a wrong guess is the fastest way to learn how that sound is built. Nothing is sent anywhere.

The Ear Bench ★ the main event

Play a sound, predict the interval or chord quality, then the bench replays it and names it exactly — every interval and chord is generated from the theory model, right on your device, no cloud. A missed ear is just where the sound surprises you.

Who you’ll meet

Not mascots — the skills of a trained musician, each one a single move you’ll practise. You’ll run into them across the kits and the bench.

  • The Sight-Reader — places any note on the staff by clef and line (staff & clefs)
  • The Timekeeper — feels where the beats fall and how they group (rhythm & meter)
  • The Interval-Ear — names the exact distance between two pitches (intervals)
  • The Key-Keeper — knows every scale by its sharps and flats (scales & key signatures)
  • The Chord-Builder — stacks thirds into major, minor, diminished, augmented (triads)
  • The Harmonist — labels a chord by its role in the key (diatonic harmony & Roman numerals)
  • The Cadence-Reader — hears how a phrase comes to rest (cadences)
  • The Transcriber — writes down a melody or rhythm just by ear (dictation)
  • The Voice-Leader — moves each line smoothly from chord to chord (voice-leading)
  • Maestra Rey — the mentor — predict the sound, play it, then reconcile

Check what you know

Sixteen short kits — from staff and clefs through note names, rhythm, intervals, scales, modes, triads, seventh chords, diatonic harmony, cadences, dictation, progressions, voice-leading, transposition, and form — anchored to high-school music theory. Hints when you want them; your progress stays on this device.

How it works

ClefQuest is written to trust you — it’s about hearing and reasoning through how music is built, not memorizing terms, and a wrong prediction is just a place to learn. The Ear Bench is a small, exact engine: it synthesizes each sound on your device (no server, nothing sent anywhere) and the answer comes from the theory model, never an opinion. Your progress is saved only on this device: no accounts, no ads.
