play music to defeat monsters
5 game modes: notes, scales, chords, perfect pitch, full song
MIDI keyboard or microphone input (guitar, voice, etc)
learn musical notation: alphabetical, do-re-mi, sheet music
play a mix of notes and chords as fast as you can to stay alive
improve your major + minor scale technique
work through a series of increasingly complex jazz chords
identify notes by ear!
import a MIDI file and battle through an entire song
the more you play, the more you level up your music skills :]
Monsters appear on screen and you defeat them by playing the correct musical notes on your instrument. Each game mode focuses on different skills: notes, scales, chords, or ear training. Play quickly and accurately to survive and level up!
MIDI (Musical Instrument Digital Interface) is a protocol that lets electronic instruments communicate with computers. When you press a key on a MIDI keyboard, it sends a digital signal that the game reads instantly, no audio processing needed.
Plug your MIDI keyboard into your computer via USB. When you start the game, your browser will ask for permission to access MIDI devices. Click "Allow" and you're ready to play. Most USB MIDI keyboards work plug-and-play with no extra drivers needed.
Yes! The game supports live microphone input for any instrument or voice. Click "Allow" when your browser asks for microphone access. The game uses pitch detection to identify the notes you play or sing in real time. For the most accurate detections, try to play notes clearly and one at a time.
MIDI mode reads digital signals directly from your keyboard — it's instant and 100% precise. Microphone mode uses pitch detection on your audio input; it works with any instrument but may have a slight delay and some missed detections. For the best experience, use MIDI.
This game works best in Chrome, Brave, or Firefox browser. MIDI device support requires the Web MIDI API, which does not work with Safari browser. Microphone mode works in all major browsers.
No special equipment required! You can use microphone mode with just your computer or phone's built-in mic. For the best experience, I recommend a USB MIDI keyboard (any budget option works) or an external microphone for acoustic instruments.
Microphone mode works on mobile devices, but MIDI mode does not currently work. For the best experience, please play on a laptop or desktop computer.
