Intonation Training

Intonation Training listens through your microphone and scores your intonation against written music, in time. A tuner shows you that one held note is 12¢ sharp — it can't tell you that you go sharp on the leap into the high register, or flat when you tire at the end of a phrase, or that C#5 has been your problem note for a month. This does. Play the exercise; the app hears every note and shows you which ones you miss. How it works for real practice: • Scored against written music, in time — eight measures on the staff, judged note by note as they pass. You train intonation the way it actually fails: in motion, at tempo, under a pulse — not one held note at a time. • Trouble notes — the exact pitches you miss most, with hit rate and attempt count. "My intonation is shaky" becomes "your C#5 is 61% over 34 attempts." Now practice has a target. • Play and Hear — Play opens the mic and scores you; Hear loops the melody through the speaker with no mic and no judgement, so you can learn how it should sound before you're graded. • Wait for me — stop for a breath and the music freezes until you play again. Silence never turns into a wall of red. • Four strictness levels — Learner ±25¢, Amateur ±15¢, Pro ±10¢, Studio ±5¢. The app grows with you, from "find the pitch at all" to studio-tight. • Brass and woodwind — eleven transpositions plus a bass-clef mode. The staff shows what you read; scoring judges the concert pitch that actually sounds. Trumpet, cornet, horn, the sax family, Bb and A clarinet, bass clarinet, flute, piccolo, oboe and English horn — plus a bass-clef mode for trombone, euphonium, tuba and bassoon. Track real progress: • Per-exercise stats — attempts, best and average accuracy, current and best streak, fastest clean tempo, and an accuracy-over-time chart. Weeks of practice become a line going up. • Badges to earn, a sample-locked metronome with an optional count-in, and auto-bump tempo that steps up on its own when you play a loop clean. • Practice reminders that ask you back. Read music your way: • Note names in letters (C D E), German (H/B), or solfège (Do Re Mi) — independent of the app's language. • Available in English, Spanish, French, German, Portuguese, Italian, Japanese and Korean. 600+ built-in exercises — major and minor scales, chromatics, pentatonics, blues, whole-tone, diminished, intervals and speed studies — plus import of song and library share codes from Trumpet Trainer, French Horn Trainer and Trombone Trainer. Free to start: • Practice and score a full built-in library for free, and listen to any exercise in Hear mode at no cost. • A single one-time unlock opens everything — scoring on all 600+ exercises, plus editing, importing share codes, and sharing your own. One purchase, no subscription. A tuner judges one note in isolation. Intonation Training scores a written line, at tempo, and remembers the result per exercise — so progress means something across weeks, not seconds.
