About this app
TRAIN YOUR INTONATION WITH PRECISION
mellowD helps beginners and advanced string instrument players systematically improve their intonation and sense of rhythm.
Play scales, randomly arranged notes, or complete pieces of music on your instrument—the app analyzes your pitch in real time and provides clear feedback on your accuracy and progress. In the PRO version, you can import and practice additional custom music pieces in .musicxml format. In orchestra mode, you will learn fast sight-reading and playing along within a virtual orchestra group.
No more guesswork. No more out-of-tune notes.
You can see instantly how cleanly you are playing. And if you are unsure which finger goes where in a given position, simply check the interactive fretboard tap!
