Tune Champ is a practice buddy for instrument learners. It removes confusion, bringing motivation and confidence. I built Tune Champ for my children. They play guitar, cello and violin. For all of them, knowing exactly how to play a note was distracting. The confusion would interrupt their practice flow. Sometimes it would leave them frustrated and demotivated, instead of encouraged and happy. With Tune Champ on your music stand, getting the right note is easy… * When you tap a note, Tune Champ will show the instrument fingerings that play that note. Tune Champ will also play that note aloud so you can hear the right sound to make. * When you play a note on your instrument, Tune Champ will show you the note you are playing, letting you double check you're hitting the one you want. * If you tap on Tune Champ’s instrument, it will show you which note that note is, and play you the sound of that note. Tap out a few notes of melody with Tune Champ to hear that phrase and check your fingerings. Then transfer to your instrument and practice confidently, knowing you’re getting the right tune. Tune Champ is currently for Guitar, Violin and Cello. Tune Champ comes with a no-subscription free-trial. Try it for 10 days and if you like it, purchase a subscription. I hope you and your music learners love Tune Champ and find it helpful!
