The ear trainer that actually listens.
Music Master 3000 plays you a lick — you play it back on your own instrument, whatever you play. Plug in a mic or audio interface and it recognises every note you play, instantly. Then spaced repetition makes sure the licks you learn stick for good. Hear it, play it back, never forget it.

We close the gap between your ear and your instrument
Most ear training happens in isolation — tapping multiple-choice answers on a screen. The skill never reaches your hands. Music Master 3000 connects the two directly: you respond on your actual instrument, so what you train is what you play.
Typical ear trainers
- ✕Multiple-choice quizzes you tap on a screen
- ✕Your instrument never enters the room
- ✕Recognising a sound ≠ being able to play it
- ✕Skills stay trapped inside the app
