Record, slow down and organize your music lessons. From Youtube or Camera.

WhatNote the Music Lessons Assistant on your mobile device
WhatNote will assist you when you are learning your music instrument. Imagine: You go to your music teacher and at the end of the lesson you record a summary what you did during your lesson. At home you can play it back, even in slow motion or frame by frame. Nothing is too fast for you anymore. Of course you can also use your clips from Youtube and play those in slow motion too. 

My Promise: I put my heart and soul in this app to make it the best dance assistant app on this planet.

We would like to encourage you to share your list with others. Your music learning playlist might benefit someone else too. Sharing is caring.
