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. EAR TRAINING FOR INTONATION Other ear trainers teach you to name intervals and chords. Tonai trains the ear you need when you play: hearing that a note is out of tune, and in which direction. No instrument, no microphone, one minute a day. • Which note is off? A melody you know plays over a drone and one note is out of tune. Find it and say if it was high or low. Levels go from 100 cents down to 5. • Higher or lower? Two notes, one tap. Two right in a row and they move closer, down to 2 cents apart. Which note is off? is a journey through 6 worlds of 5 levels. Pass each world's exam to earn a title, from Novice to Legend. The path and its ranking start again on the 1st of every month, with new melodies. THREE DAILY CHALLENGES The two ear games sit next to Scales and arpeggios, which you play on your instrument: a new scale and its arpeggio every day. Win bronze, silver or gold and climb through all 24 keys, the 12 majors and then the 12 melodic minors, in one, two or three octaves. ONE SCORE, ONE GLOBAL RANKING Your AI sessions, your scale challenges and both ear games add up to one overall score, with its history over time and your practice streak. See your place in the global ranking of Tonai players, anonymously or with the name and country you choose.
