By clicking the "b" button you will only listen the Piano / Keyboard. You can click on the bar from which you want to repeat. QUIZZES SECTION (Seventy quizzes): Each Quiz is related to a lesson.

In the same way as reading guitar music, flute music, violin music or bass music, all require practice; reading Piano / Keyboard becomes easier if you practice it on a daily basis. Knowing how to read music is very useful if you get Piano lessons. Being able to understand a music score helps you to get a better understanding of any type of Piano music styles. Practicing is the key and this app has been created to let you practice reading piano sheet music anywhere at anytime. Music notation for piano, organ or any type of keyboard is the same. Just as a guitar player becomes better if he practices reading guitar sheet music, a piano playr becomes better if he practices reading piano sheet music.
