How It Works
Each note is synthesised using the Web Audio API. The recorder sound uses a combination of a flute-like sine wave with gentle breath noise — a short burst of filtered white noise that mimics the airy attack of a real recorder's windway. The tone decays naturally with a smooth exponential envelope. A synthetic reverb impulse response adds room ambience when enabled. The screen recorder captures your performance as a WebM video that you can download locally.
Frequently Asked Questions
What is a recorder instrument?
A recorder is a woodwind instrument played by blowing air into the mouthpiece and covering holes to change pitch. It comes in soprano, alto, tenor, and bass sizes. The soprano is the most common and widely used in schools worldwide.
What is the difference between soprano and alto recorder?
The soprano recorder is smaller and plays in a higher register (starting C5), while the alto recorder is larger and plays lower (starting F4). Soprano is more common for beginners and school music.
What notes does the soprano recorder play?
The soprano recorder typically covers C5 to D7 — two full octaves plus two notes. This virtual instrument covers all the main notes used in beginner and intermediate recorder music.
Can I use a keyboard to play?
Yes — keyboard keys are shown on each note button. The keys run left to right across the note range so you can play melodies without lifting your hands from the keyboard.
Does it work on mobile?
Yes — the note grid is fully touch-friendly and scales to your screen width. Tap any note button to play it. Works on both portrait and landscape orientation.
What is the solfège equivalent for recorder notes?
Using C as Do: C=Do, D=Re, E=Mi, F=Fa, G=Sol, A=La, B=Ti. The soprano recorder starting on C5 maps perfectly to the standard solfège notation used in Western music education.
