Ear training, taken seriously
Learn to hear what you play.
41 structured exercises for intervals, chords, harmony, rhythm and notation. Adaptive difficulty, real instruments, free.
No sign-up needed · Sound on
Try it · what interval is this?
Two notes, one after the other.
Press play, then answer.
Built like a practice method, not a quiz.
Every answer feeds a per-skill rating. The next question arrives at the difficulty where you learn fastest, right at the edge of what your ear already knows.
Adaptive by design
Questions are chosen so you succeed about seven times in ten. Hard enough to grow, steady enough to stay.
Real instruments
Sampled piano, guitar, flute and trumpet, plus pure tones for a timbre-free challenge. Switch any time.
Free, entirely
All exercises, all learning content, the leaderboard. No paywall, no advertising, no upsell screens.
What you can train
25 listening modes on the web, 25 of them with timed challenges and a global leaderboard.
Common questions
Is Tavi La Si free?
Yes. All exercises, the adaptive practice system, the leaderboard and all learning content are free, with no ads and no paywall. Optional avatar cosmetics in the app are earned by playing, never bought.
Do I need an account to practice ear training here?
No. Everything on the website works without signing up; practice stats are stored in your browser. A free account (in the app today) adds progress sync, XP, streaks and the leaderboard.
How does the adaptive difficulty work?
Every answer updates a per-skill rating (an Elo system). The next question is chosen so you succeed about 7 times in 10, which is the fastest zone for learning recognition skills.
What is the difference between the website and the Tavi La Si app?
The website has the full listening trainer, learning content and leaderboard. The Android app adds a playable piano, a drum pad, tap-precision rhythm training, melodic dictation and practice reminders.
