Flappy Note

A singing game where you control a bird by matching pitches. Guide the bird through gates by singing the target notes displayed on each gate.

How to Play

Click Start Game and allow microphone access when prompted
The bird follows your voice - sing higher to go up, lower to go down
Each gate shows a target note (Do, Re, Mi, etc.) - sing that note to pass through
Match the pitch shown on the gate to score points
The game ends if you miss a gate or go off-screen

Tip: Start with the Major Scale on a comfortable root note (like D or E). Enable the Root Drone to help you hear the tonal center.

Settings

Setting	Description
Root Note	The tonal center of the scale. Choose based on your vocal range.
Mode	The scale or chord pattern to practice. Start with Major Scale.
Direction	Ascending (up), Descending (down), or Random order of scale degrees.
Root Drone	Plays a sustained root note for pitch reference.

Scoring

Pass through a gate while matching the pitch = +1 point
The closer you are to the target pitch, the better
Try to complete the full scale without missing any gates

General Tips

Getting Better Pitch Detection

Sing clearly with good breath support
Avoid very quiet or very loud singing
Use headphones to prevent the drone from interfering with detection
Find a quiet room with minimal background noise
Hold your device at a consistent distance from your mouth

Practice Suggestions

Start simple - Begin with Major Scale ascending before trying modes or chords
Use the drone - It helps establish the key center in your ear
Slow down - Focus on accuracy over speed
Record yourself - Use Vocal Monitor to spot patterns in your intonation
Practice intervals - Try 7th chords to work on larger jumps
