Scale Ètude

Train your ear and master every scale. Identify scales by sound or build them note-by-note in any key, and track your progress - for any instrument.

Scale Etude helps you truly learn your scales — not just memorize shapes, but hear them, spell them, and own them in every key. It's built for any instrument: everything is by ear and by note name, so it works whether you play guitar, piano, sax, or anything else.

TWO FOCUSED DRILLS

• Identify by ear — hear a scale played and name which one it is. Train your ear to recognize the sound and color of each mode.

• Build the scale — given a scale and key, tap every note that belongs. Learn the correct spelling of any scale in any of the 12 keys.

Everything uses strict music-theory spelling, so you learn scales the right way — A Phrygian is A, Bb, C, D, E, F, G (never A#), with each degree getting its proper letter name.

EXPLORE AND UNDERSTAND

• A browsable library of 11 scales — the 7 modes (Ionian through Locrian), major and minor pentatonic, and major and minor blues.

• A detail view for every scale with an interactive interval wheel, a note-by-note breakdown, step formulas, and the character of each scale.

• Hear any scale or single note played on a clean, sampled instrument.

PRACTICE YOUR WAY

• Focus on exactly what you want — a whole family, a handful of scales, or a single scale drilled across all 12 keys.

• Turn on Race the Clock to answer against a timer and build fluency under pressure.

• Adaptive mastery tracking surfaces your weakest scales first, so every session targets what you actually need.

PRIVATE AND OFFLINE

• No account, no sign-up, no ads.

• Works fully offline and keeps all your progress on your device.

Whether you're a student nailing your modes, a guitarist breaking out of the pentatonic box, or a jazz player internalizing every key, Scale Etude makes scale practice focused, fast, and genuinely effective.
