This online piano website recreates the essence of piano playing using modern browser technology:

Authentic Sampling: Utilizes multi-level velocity-sampled sound sources from a professional grand piano, ensuring pure, clear timbre with realistic resonance.
Polyphony Support: Supports pressing multiple keys simultaneously (chord playing) without audio clipping or note cutoff.

Keyboard Control: Features a scientifically designed key mapping for PC users. The letter and number keys on a computer keyboard simulate the white and black keys, supporting multi-finger legato playing.
Touch Feedback: Supports multi-touch on mobile devices, with key press animation for a responsive feel.
MIDI Support: Compatible with external USB MIDI keyboards. Once connected, it can directly drive the webpage's sound source, offering an experience closer to a real piano.

Key Display: Freely toggle key labels (e.g., C, D, E or 1, 2, 3) on or off to lower the entry barrier.
Octave Shift: Supports one-click octave shifting, quickly covering the full range from the contra octave to the treble octave.

Real-time Recording: Supports recording your performance as an audio file or MIDI sequence for easy saving and sharing.

Enable Sound: Ensure your device is not muted. Using headphones is recommended for better bass resonance.
Choose Operation Mode:
- PC: Use the middle two rows of letter keys for playing (the tool interface shows the corresponding mapping).
- Mobile: Directly tap the piano keys on the screen in landscape orientation.
Adjust Settings: Turn on "Show Note Names" or switch "Instrument Sounds" (e.g., electric piano, organ) as needed.
Start Playing: Try pressing keys like A-S-D to experience the low-latency trigger feedback.

Zero-Latency Engine: Utilizes Web Audio asynchronous loading technology, solving the traditional webpage instrument pain point of "no sound on press" delay.
No Installation, Ready to Use: No need to download large VST plugins or apps; your browser is your piano classroom.
Clean & Uncluttered: Simple interface with no pop-up ads, ensuring high concentration during your performance.
100% Privacy & Security: The recording function runs locally. Your recordings will not be uploaded to any server without your permission.
