Music notes training for piano

It is an application to train so that you can read music score, such as piano, and staff score. In this application, we try to train at wide range (3 octaves) at once. (Please think that the star of the keyboard and the star mark of the score are the center of the piano.) Training with a note sign is on the right hand, training with a note is training with the left hand, I think I can practice with a sense close to the piano. · How to use Because we focused on practicing in a wide range, the keyboard is narrowing, If the place you touched first was not the place you wanted, you can slide your finger to select the keyboard. · Result screens and score After practice, results of exercises are to be seen. o is a correct answer, x is incorrect answer, △ is a correct answer, but it took over 3 seconds to answer. If you touch each keyboard, the score corresponding to the keyboard will come out, so let's check out where we are weak. · About release of mode In the initial state, only C major is available for selection. Each mode can be released at points that can be acquired at the time of clearing. Points are determined by Rank determined by clear time and correct answer within 3 seconds, Please aim for the Rank Master.
