Music score and piano roll notation make it fun and easy to learn!

Chordana Play displays the music score and piano roll notation for built-in songs and MIDI files. With MIDI files, you can select which tracks to play with your left and right hands, or you can assign the melody to the right hand and chords generated by the app to your left hand. Slow the tempo down, transpose to a key that is easier to play, and with the AB repeat function, take lessons (practice) at your own pace.
You can take three-step lessons using the virtual on-screen keyboard. Select from 128 kinds of tone quality. Plus, a scoring system lets you keep track of your progress.

    ♦If using right-hand (melody) and chord data, up to approximately 720 notes of the right-hand part can be transferred to the keyboard, assuming two chords per measure for 200 measures.
    ♦If using right-hand (melody) and left-hand (accompaniment) data, up to approximately 960 notes can be transferred.
    ♦If non-note MIDI data (patches, pedals, etc.) is included, this reduces the number of notes that can be transferred, leading to potential errors even if the approximate limit of 720 or 960 notes is observed.
