Scale Ètude

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.
