Roughly one in six adults believe they are tone deaf. Measured, the real number is closer to one in sixty-five. Musicality is built for the gap between those numbers: for everyone who quietly decided music was not for them, based on nothing.

You are not tone deaf. You are untrained. There is a difference, and you can hear it for yourself in three minutes a day.

What an interval is

An interval is the distance between two notes. The difference between a happy chord and a sad one is one semitone. There are thirteen of them, from the prime to the octave, and they are what Musicality teaches.

You answer by playing

Musicality plays a note and you play it back by ear, scored on pitch and timing, beat by beat. You are never asked to name what you heard. You need no instrument of your own. If you have a piano or a guitar, turn on the microphone and answer on that instead.

Play along with the record

Both albums play inside the app with the melody drawn as it sounds: on the page, on a piano keyboard, or on a guitar neck. Turn on the microphone and your own pitch appears beside the melody, so you can see where you landed. Training tracks play from half speed to one and a half.

Two albums

Basic Training and Sticky Tunes: twenty-six tracks composed for this app by Ruud Vleij. Every interval gets a Training that teaches the distance and a Tune that makes it stick. A tune never leaps further than the interval it teaches, so remembering the tune means remembering the interval. The tracks play like any album: press play and simply listen, no instrument needed.

Three minutes a day

The daily session is three minutes. That is the whole design, not a trial. Ear training works because it is short and it is daily, and a session you finish is worth more than one you abandon.

What is free and what is not

Four intervals are free and complete: both their tracks, and all of Play Along. One purchase opens the other nine, lifts the clock, and brings interval training into your daily session. It is bought once, not a subscription.
