About this app
Have you ever wanted to learn how to read music? This app helps you make the associations between the notes on the page and the keys on the piano by feeding notes to you one by one randomly. You can adjust the speed that the notes will play, and you can change the highest and lowest note. Sounds will play with each note for you to play along with!
