Relative Pitch: Intervals

The app is free. Level 1 in full, with unlimited sessions, and training that adapts to your ear from the very first answer.

You hear two notes. Which one is higher? By how much? And played together, could you name them?

Recognizing intervals by ear is what separates the musician who reads notes from the one who hears music. It is not a gift, it is practice. And you do not need to read sheet music to start.

TRAINING THAT ADAPTS TO YOU
The ZDP engine reads your answers as you go and sets every exercise to the level you are at today. On a good run? Difficulty rises. An interval that keeps slipping? It eases off until that one sinks in. You stay where progress actually happens: never bored, never stuck against a wall.

A DEBRIEF AFTER EVERY SESSION
Apple Intelligence can analyze your work right on your device and give you personal feedback: what is settling in, what still needs time. Nothing leaves your device.

YOUR DATA STAYS WITH YOU
No collection, no account to create, no connection required, no permission to grant to get started. Everything happens on your device.

Note Precision: Intervals accompanies the Relative Ear module of the L.U.C.I.D. platform, which grew out of a music teacher's work, and it fits practice with your teacher as naturally as working on your own at home.

Available in 12 languages, as a native app on iPhone, iPad and Mac. This is the first app in the NotePrecision suite.

The ear can be trained.
