Tonai – AI Intonation Coach

Tonai is the practice companion that helps musicians master the hardest skill of all: playing in tune. Built for everyone who shapes their own pitch: strings, woodwinds, brass and voice. Just play. Tonai listens to every note, shows you exactly where your intonation drifts, and tells you what to fix next. AI MUSIC ANALYSIS The heart of Tonai. Tap the orb and play a melody, a passage, anything. The moment you stop, you get a full report: a score out of 100, every note on the staff colored by how well you tuned it, and the exact deviation in cents. Then your AI coach tells you, in plain words, the one thing to work on next. Like having a teacher listening in. DAILY CHALLENGES A scale and its arpeggio, new every day. Win bronze, silver or gold and climb through all 24 keys: the 12 majors, then the 12 melodic minors, in one, two or three octaves. After every attempt you get a short AI note on what went well and which note to watch. YOUR INSTRUMENT, YOUR NOTES Play sax, clarinet, trumpet or horn? Tonai shows note names and staves as written on your part, or at concert pitch if you prefer. Soprano, alto, tenor and baritone sax are all supported, and keys are spelled the way you read them: Bb major, not A# major. WATCH YOUR TUNING IMPROVE Your score over time, your personal records, your practice streak and the full history of every key. A clear, honest picture of your progress.
