Learn your favorite songs.

1. 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, transpose the score into 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 improving skills.

2. Use the 50 built-in songs or import standard MIDI files
Play one of the 50 songs included in Chordana Play, or add MIDI files.
Chordana Play can generate a music score from the MIDI file and detect chords, too, making it easy to learn to play two-handed piano. You can search for MIDI files using the browser on your smartphone or tablet (smart device), then import them into Chordana Play. Plus you can import MIDI files from a personal computer to Chordana Play.

3. Practice anytime and anywhere
Using either the app's keyboard or a USB-connected musical instrument keyboard, you can take a three-step lesson while following the music score and piano roll. The scoring feature makes mastering a song even more fun.
