Notes glide across the staff. Play each one before it reaches the edge, using the on-screen piano or a compatible MIDI keyboard.

🎵 Adaptive practice
The app measures your answer time and gives more practice to the notes that take you longest to recognize.

⚙️ Adjust the practice to your level
• Choose how fast the notes move.
• Limit the range of notes you practice.
• Practice sharps and flats by changing the key signature.
• Choose how many notes can be visible at the same time.

🎼 Treble and bass clef
Practice the treble clef for free. The bass clef is available as an in-app purchase.

🆎 Several note naming systems
• C-D-E-F-G-A-B
• C-D-E-F-G-A-H
• Do-Re-Mi (Si or Ti)
• Byzantine
• Japanese
• Indian

🎹 MIDI support
You can use a compatible MIDI keyboard instead of the on-screen piano. Connecting usually requires a USB OTG adapter. Because Android devices and manufacturers differ, MIDI support may not work on every device.
